Fodor's Expert Review Purple Onion

This funny house ranks right up there with Bimbo's and the Fillmore on the list of San Francisco's most famous clubs, and people seem to love it or hate it. Regardless, the Onion is a historic, quintessential San Francisco institution that provided an early platform for both folk-music troubadours such as the Kingston Trio and comedic acts like Robin Williams. In addition to stand-up, you can catch sketch comedy, open mike, and improv shows.
