***** Chicago, the fifth-largest city in North America—yes, North America—is a city blessed with world-class live entertainment. From theatre to jazz, opera to stand-up, this city pulses with creativity. But nestled within the now-thoroughly gentrified Lincoln Park neighborhood is a comedy institution that somehow still feels like a hidden gem: the newly revitalized iO Theater.
For decades, iO (formerly ImprovOlympic) has been an incubator for comic genius, giving early stages to legends like Stephen Colbert and Amy Poehler. Reopened and reinvigorated, the iO building today is more than a theater—it’s a multi-level hub for performance, training, social events, and even weddings. That’s right—corporate meetings by day, cocktails and punchlines by night. It’s the kind of place where laughter echoes through the stairwells seven nights a week.
The iO Theater operates multiple stages, offering a rotating slate of performances and classes. Whether you’re a student of comedy or just someone who needs a good laugh after work, this is your place. Improv happens nightly across their different studios, and you’re not just witnessing comedy—you’re part of the community.
Last night, I caught the closing performance of Duluth, a longform narrative improv show inspired by the dark humor of the FX hit series Fargo. Each week, the cast built an entirely new story of small-town murder and mayhem, pulling a hometown suggestion from an audience member. The results? A mix of twisted plots, deadpan detectives, bumbling criminals, and that peculiar brand of passive-aggressive charm known as “Minnesota nice.” It was chillingly funny and impressively cohesive, especially considering nothing was scripted.
For the uninitiated, there are three major types of improv: shortform (think games and quick scenes), narrative (a single improvised storyline), and longform (which includes narrative, but also Harold and montage styles). Duluth exemplifies longform improv at its best—fewer audience prompts, more ensemble trust, and the kind of timing that only comes from seasoned actors reading each other’s minds.
The venue enhances the experience. Done cabaret-style, the shows are viewed from small tables with cocktail service. The drinks? Delicious and reasonably strong. The food? Small bites that pair perfectly with laughter. It’s casual, intimate, and completely engaging. Whether you’re a regular or a first-timer, you’ll feel like you belong.
While Duluth may have ended its run on July 17, the iO calendar is always full, with new and returning shows weekly. I strongly recommend keeping an eye on their lineup at www.ioimprov.com, or call 312-300-3350 for reservations.
Having seen my fair share of improv in Chicago—including at Second City—I can honestly say I laughed harder last night than at many mainstages shows. This isn’t just a place for comedy fans; it’s a home for laughter lovers, budding performers, and anyone in need of a good time.
The IO Theater is located at 1501 N. Kingsbury ( just south of North Avenue/Clybourn/Halsted area)
Don’t miss this five-star gem of Chicago. iO Theater is back—and better than ever.
