There was a time when people were afraid that "The Biz" would be a victim of its own success. The Valley's oldest lesbian bar is also its best-known, and if straight people know about only one gay bar in the city, it's The Biz. But what makes this bar so popular for people of any sexual orientation is not just the promise of hordes of hot women writhing together on the dance floor. The DJs, Tsunami and Suzy, spin the hottest mixes of hip-hop, house, Top 40 and retro, and the bartenders serve up drinks faster than you can say the L-word, not to mention the slew of sexy shows (the band Betty, musician Jennifer Spector, and drag kings) and erotic events (wet tee-shirt contests and "Stripper Night"). But don't take our word for it. Show up on a Thursday or Sunday night and see for yourself. Just be prepared to stand in line if you show up after 10 p.m.
