This is the club that all the big names, from Coldplay to Clapton, want to play. San Francisco's most famous rock-music hall presents national and local acts: rock, reggae, grunge, jazz, folk, acid house, and more. Go upstairs to view the amazing collection of rock posters lining the walls. At the end of each show, free apples are set near the door, and staffers hand out collectible posters. Avoid steep service charges by purchasing tickets at the club's box office on Sunday from 10 to 4.
