How to Book iO Improv Show Chicago

The iO Theater in Chicago is more than just a comedy venue—it’s a cultural institution and the birthplace of some of the most influential improvisational theater in the world. Founded in 1981 by Charna Halpern and Del Close, iO (formerly ImprovOlympic) has launched the careers of countless comedians, writers, and performers who now dominate television, film, and theater. From Tina Fey and Amy Poehler to Stephen Colbert and Jason Sudeikis, the iO stage has been a proving ground for comedic genius.

Booking an iO improv show in Chicago isn’t just about securing a ticket—it’s about immersing yourself in the raw, unscripted energy that defines Chicago’s improv scene. Whether you’re a first-time visitor or a longtime fan, knowing how to navigate the booking process ensures you don’t miss out on the best performances, intimate late-night sets, or exclusive ensemble showcases. This guide walks you through every step of the process, from understanding show types to choosing the right night, and reveals insider tips to maximize your experience.

Step-by-Step Guide

Understand the iO Theater Structure and Show Types

Before you book, it’s essential to understand the different types of shows offered at iO Chicago. Unlike traditional theater, improv performances are dynamic and change nightly based on audience suggestions and performer chemistry. The theater typically runs multiple shows per night across two stages: the Main Stage and the Basement Stage.

On the Main Stage, you’ll find long-form improv shows, often performed by professional ensembles that have trained for years. These include signature formats like “The Harold,” a complex, multi-scene improvisational structure developed by Del Close. Shows here are more polished and often feature performers who are alumni of the iO training center.

The Basement Stage hosts more experimental and emerging acts. This is where new student teams debut, and where you might catch the next big name in improv before they hit the mainstream. Shows here are often more raw, unpredictable, and intimate.

Additionally, iO offers themed nights such as “ComedySportz,” “Theatresports,” and “Improv Olympics,” which vary in format and tone. Some nights feature guest performers from other improv theaters or national tours. Always check the show description on the website to understand the style and level of performance you’re signing up for.

Visit the Official iO Theater Website

The most reliable and up-to-date source for show schedules and ticketing is the official iO Theater website: iochicago.com. Avoid third-party ticket resellers—they often charge inflated prices, and may not offer valid seating or access to special events.

Once on the site, navigate to the “Shows” tab in the top menu. Here, you’ll find a comprehensive calendar view of upcoming performances. Each listing includes the show title, stage, date, time, duration, and a brief description. Hover over or click any show to view details such as the performing ensemble, whether it’s student-led or professional, and if there are any age restrictions.

Be aware that show times vary. Weekday shows typically start at 7:30 PM and 9:30 PM, while weekend shows may run from 7:00 PM to 11:00 PM with multiple performances. Late-night shows (after 11:00 PM) are often more experimental and attract a younger, more adventurous crowd.

Choose Your Show Based on Your Preferences

Your experience will vary dramatically depending on the show you choose. If you’re new to improv, start with a Main Stage performance like “The Harold” or “The Armando.” These shows are structured, well-paced, and easier to follow for newcomers. They also tend to have higher production value and more experienced performers.

If you’re looking for something edgy, unpredictable, and authentic, opt for a Basement Stage show. These are often free or pay-what-you-can, and you’ll get to witness performers in their formative stages. Many of these shows are created by current students of the iO Training Center, so you’re seeing live, evolving art.

Consider the theme: Some shows are based on audience suggestions (“Audience Suggested Harold”), while others follow a narrative arc or character-driven format. If you enjoy musical improv, look for “Musical Harold” or “The Show Must Go On.” For fans of sketch comedy blended with improv, check out “The Second City” alumni shows or “Theater Sports.”

Check for Special Events and Seasonal Programming

iO Chicago frequently hosts special events that are not part of the regular rotation. These include:

• Improv Festivals – Held twice a year (Spring and Fall), these multi-day events feature dozens of local, national, and international improv teams.
• Anniversary Shows – Celebrations of iO’s founding often include legendary alumni returning to the stage.
• Themed Nights – “Holiday Improv,” “Superhero Night,” or “Movie Parody Nights” offer fun, genre-specific performances.
• Workshop Showcases – Free or low-cost performances where training center students present their final projects.

These events often sell out quickly and may require early registration or special access. Subscribe to iO’s newsletter or follow their social media channels (Instagram, Facebook, Twitter) to get notified about upcoming special events. Many of these shows are not listed on the main calendar until just days before they occur.

Reserve Your Tickets

Once you’ve selected your show, click the “Book Tickets” button next to the performance. You’ll be directed to a secure ticketing portal powered by a third-party system (usually TicketTailor or Eventbrite). Here, you’ll choose:

• Number of tickets (typically 1–6 per transaction)
• Seating preference (front, middle, or back; note that iO has limited seating and is first-come, first-served within sections)
• Whether to add a drink voucher (highly recommended—see Best Practices below)

Ticket prices vary by show type and stage. Main Stage shows typically range from $15–$25. Basement Stage shows are often $10 or less, and some are “pay what you can” with a suggested minimum of $5. Special events and festivals may cost $25–$40.

Payment is processed via credit or debit card. You’ll receive an email confirmation with a QR code or ticket number. You do not need to print your ticket—digital tickets are accepted at the door. However, keep the email accessible on your phone, as Wi-Fi can be spotty in the theater’s basement location.

Arrive Early and Understand the Venue

iO Chicago is located at 1501 N. Kingsbury Street, in the Lincoln Park neighborhood. The building is unassuming—look for the small, dark sign with the iO logo. The theater is underground, literally and figuratively. Once you enter, descend the stairs to the lobby, where you’ll find the box office, bar, and restrooms.

Arrive at least 20–30 minutes before showtime. iO does not hold seats; seating is first-come, first-served. Arriving late means you risk sitting in the back row or standing. The theater is small—only about 100 seats total across both stages—so even a 10-minute delay can impact your view.

There is no coat check, so bring only what you can carry. The basement can be chilly, even in summer, so a light jacket is advisable. There is no parking on-site. Street parking is limited and metered. The closest public parking garage is at 1515 N. Wells Street (just two blocks away). Consider using rideshare services like Uber or Lyft, which drop off directly in front of the building.

Understand the Show Etiquette

Improv is interactive. Audience members are often asked to shout out suggestions for scenes, locations, or emotions. This is part of the magic. Don’t be shy—your suggestion might become the foundation of a 20-minute scene.

However, there are rules:

• Do not shout out specific jokes or lines. Suggestions should be simple: “A pirate,” “A dentist’s office,” “A wedding,” “A talking dog.”
• Do not record video or audio. iO has a strict no-recording policy to protect performers’ intellectual property.
• Turn off your phone completely. Even a notification light can distract performers.
• Applaud enthusiastically. Improv thrives on energy. Your laughter and clapping fuel the performers.

After the show, many performers hang out near the bar. It’s common—and encouraged—to say hello, thank them, or even ask for advice. Many performers are happy to chat with fans, especially if you’re interested in taking a class.

Best Practices

Book Early—Especially for Weekends

Weekend shows at iO sell out fast. Friday and Saturday nights are the most popular, particularly during tourist season (May–September). If you’re visiting Chicago for a weekend getaway, book your tickets at least one week in advance. For special events or festivals, book two to three weeks ahead.

Set a calendar reminder to check the website every Monday morning. New show schedules are typically posted on Mondays for the upcoming week. The earlier you book, the better your seating options.

Opt for the Drink Voucher

Most ticket packages offer the option to add a drink voucher ($5–$7). This is a smart move. iO’s bar serves quality cocktails, local craft beers, and wine at reasonable prices. Without a voucher, drinks cost $8–$12. The voucher gives you one drink of your choice, and you can use it before or after the show.

Many performers appreciate audience members who support the bar. It helps keep ticket prices low and the theater financially sustainable. Plus, having a drink in hand helps you relax and enjoy the show more fully.

Arrive with an Open Mind

Improv is not stand-up comedy. There are no punchlines written in advance. The humor emerges from spontaneity, vulnerability, and emotional truth. Some scenes may feel awkward, slow, or strange. That’s okay. That’s the point.

Approach each show as an experiment in human connection. The best improv doesn’t make you laugh the hardest—it makes you feel something unexpected: empathy, nostalgia, absurdity, or awe.

Consider Taking a Class

If you’re serious about understanding improv, consider enrolling in a beginner class at iO. The theater offers 8-week courses in “Improv 101,” “Writing for Improv,” and “Character Development.” Many of the best performers in Chicago started as students here.

As a student, you’ll get priority access to student showcases and discounted tickets to Main Stage shows. Plus, you’ll gain insight into the techniques that make iO’s style unique. Many students say the class experience is more transformative than any show they’ve ever seen.

Follow the Performers

Many iO performers maintain active social media profiles. Following them on Instagram or Twitter gives you insight into upcoming gigs, side projects, and new shows. Some performers announce pop-up shows at local bars or art spaces that aren’t listed on the iO website.

Join the iO Alumni Facebook group. It’s a private community where former students share news, collaborate on new projects, and promote each other’s work. You might find out about a secret show happening in a bookstore or a rooftop garden.

Explore the Neighborhood

iO is located in Lincoln Park, one of Chicago’s most vibrant neighborhoods. Before or after your show, explore nearby restaurants like The Green Door Tavern (a historic pub), The Violet Hour (a craft cocktail bar), or The Purple Pig (for Mediterranean small plates). Many locals treat an iO show as part of a full evening out.

Walk around the area after the show. The neighborhood is safe, well-lit, and full of character. You might even stumble upon an open mic night or a jazz performance in a basement lounge.

Real Examples

Example 1: A First-Time Visitor’s Experience

Sarah, a college student from Boston, visited Chicago for a weekend trip. She’d heard about iO from a friend who studied theater. She booked tickets for a Friday night Main Stage show: “The Harold” by the ensemble “The Night Owls.”

She arrived 30 minutes early, bought a drink voucher, and sat in the middle row. The show began with audience suggestions: “a librarian,” “a haunted toaster,” and “a wedding in space.”

What surprised Sarah was how emotionally resonant the scenes became. One moment, a character was crying because their toaster had died. The next, the entire cast was floating in zero gravity, singing a wedding song. The transitions were seamless, the energy electric.

After the show, she chatted with one of the performers, who invited her to a free student showcase the next night. She went, and ended up taking an 8-week improv class during her stay. “I didn’t come to learn improv,” she said. “I came to laugh. I left feeling like I’d seen something alive.”

Example 2: A Local’s Routine

Marcus, a Chicago native and iO alum, attends a show every Tuesday. He works in marketing and uses improv as his creative reset. He doesn’t always buy tickets—he often waits for the 11:30 PM “Pay What You Can” show on the Basement Stage.

He brings a friend, orders two beers, and sits in the back. He says the late-night shows are where he sees the most daring work. “You see people take risks you’d never see on TV. One night, a guy did a 15-minute scene as a sentient pile of laundry. It was ridiculous. It was perfect.”

He now volunteers as a stage manager and occasionally helps cast new student teams. “iO gave me confidence,” he says. “It taught me how to say ‘yes’ to life—even when it’s weird.”

Example 3: A Festival Attendee’s Journey

The Johnson family from Milwaukee attended the iO Fall Improv Festival. They bought a $60 pass for all weekend shows. Over three days, they saw 12 performances across both stages, including a team from Toronto, a group from Austin, and a surprise reunion of iO’s original 1980s ensemble.

They ate at nearby restaurants, took photos with performers, and even joined a free “Improv for Families” workshop on Sunday afternoon. Their 10-year-old daughter performed a scene with a professional about “a robot who loved broccoli.”

“We thought it was just comedy,” said Mr. Johnson. “We left understanding creativity. My daughter now writes her own plays.”

FAQs

Can I buy tickets at the door?

Yes, but only if the show hasn’t sold out. Popular shows—especially on weekends—often sell out online before doors open. Buying in advance guarantees your seat.

Are there student discounts?

iO does not offer formal student discounts, but student-led shows on the Basement Stage are often $5–$10. If you’re enrolled in a class, you may receive discounted or free tickets to showcases.

Is iO Chicago wheelchair accessible?

Yes. The theater has an elevator to access the basement level. Contact the box office in advance to request accessible seating. Restrooms are ADA-compliant.

Can I bring children?

Most shows are appropriate for ages 13 and up. Some late-night or experimental shows may contain adult themes. Always check the show description for content warnings.

Do performers take photos or sign autographs?

Many do—especially after student shows. Always ask politely. Avoid interrupting performers during breaks or while they’re on break. The best time is after the show, near the bar.

What if I’m late to the show?

Once a show begins, doors are locked for the safety and focus of the performers. You’ll be seated at the next intermission, if there is one. Most improv shows have no intermission, so being late means you miss the beginning—and possibly the best part.

Can I suggest an idea during the show?

Yes, but only if the performer asks for suggestions. Never shout out unsolicited ideas. Wait for a moment when the host says, “What’s a place?” or “What’s an object?” Then shout your idea clearly. One word is best.

Is there food at iO?

No. iO is a theater, not a restaurant. You can bring in a sealed water bottle. There are many nearby restaurants and cafes.

How long do shows last?

Most shows run 60–75 minutes. Late-night shows may be shorter (45 minutes). Always check the scheduled runtime on the website.

Can I reschedule or get a refund?

Tickets are non-refundable but may be exchanged for another show of equal or lesser value if requested at least 24 hours in advance. Contact the box office via email at boxoffice@iochicago.com.
