Famous for helping make sex shops respectable, Good Vibrations has become a San Francisco institution since founder Joani Blank decided it was time to bring sex toys out of the closet in 1977. (Besides the flagship store, there's another one in Berkeley.) There's certainly no other place we know of where one can shop for massage lotions, designer condoms, and naughty books and videos while enjoying a rotating display of erotic art. There's even a collection of antique vibrators. The store offers educational workshops and publishes a popular newsletter called -- what else? -- Good Vibes. Hours: Sunday through Wednesday noon to 7 p.m.; Thursday through Saturday 11 a.m. to 8 p.m.
