As San Francisco’s longest-running comedy club, Punch Line has played host to celebrity comics such as Ellen Degeneres and Robin Williams, and continues to bring established and emerging stars to its stage, which features a mural of San Francisco as a backdrop. Showcase night is Sunday, when 15 local comics take the mic to try out new material. Doors open at 7pm and shows are Sunday to Thursday at 8pm, Friday and Saturday at 8 and 10pm (18 and over; 2-drink minimum).
