Concierge.com's insider take:
Formerly called the Improv Olympics, the I.O. is the city's "other" famous comedy club (it plays second fiddle to the better-known Second City). Upstairs you'll find stadium seating in the Del Close Theater, where the set shows are performed, while downstairs, the Cabaret Theater's tables have room for around 100 people. It's here you'll find the improv for which the club is famous. The experience here is far more intimate than at Second City; you feel like you're practically on stage with the comedians. Drinks and pizza are available in both theaters.
Performance times vary; call ahead.
