fun place to dance The Stud is probably my favorite (gay) place to dance in SF. I only really go on Saturday nights for "Sugar" but they have great DJs and a really nice crowd.
Great place for dancing The Stud is a long standing icon in the gay club scene. They've been capable of continued popularity (which is rare in the club business) due to the fun dance scene and friendly atmosphere. Whatever your favorite type of music is, they've got a night for it from fun and funny Trannyshack on Mondays, sexy funky tribal Blend on Thursdays, house at Sugar on Saturdays and more.
You're guaranteed a great time no matter which nights you go--just be prepared to shake your booty and have fun.
