The Improv features headliners on the national comedy-club circuit as well as comic plays and one-person shows. Shows are about 1 1/2 hours long and generally include three comics (an emcee, a feature act, and a headliner). Showtimes are at 7, 7:30, or 8pm Tuesday through Sunday, with a second show at 9:45pm or later on Friday and Saturday. Sometimes the club adds a third show at 11pm on weekends. Acts also take place in the more intimate 60-person lounge. You must be 18 to enter.
