A comedy club is a venue—typically a nightclub, bar, or restaurant—where people watch or listen to performances, including stand-up comedians, improvisational comedians, impersonators, magicians, ventriloquists, and other comedy acts. The term “comedy club” usually refers to venues that feature stand-up comedy, as distinguished from improvisational theatres, which host improv or sketch comedy, and variety clubs (which may also host musical acts).
