Laugh Out Loud Theater (formerly the Chicago Comedy Co Theater) at the Streets of Woodfield Mall (601 N. Martingale Road, Suite 171, Schaumburg, IL).
There are two shows, one at 7:30 and one at 9:30. Both shows are short-form improv. The early show is family-friendly ("G - PG" as they say), the later show can be just a little more racy (PG-16, if there was such a thing).
