Widely considered to be the premier venue for long-form improvisational performances and classes, the iO Theater (formerly known as the ImprovOlympic Theater) was founded in 1981 by Charna Halpern and the late great improvisational teacher and director, Del Close. We have shows 7 nights a week with a full kitchen and bar. This is Chicago’s Best Improv Comedy.
