Done up in white and designed right down to its toes, Fluid Ultra Lounge is one San Francisco club that feels more like it should be in Miami. Fluid starts with a futuristic island bar glowing from within and backed by a wall of white couches, with some lounges for reclining and drinking, and some for dancing. Fluid moves. As you pass the bathrooms, you enter a den of funk, where a roster of mostly A-list DJs spin to an enthusiastic crowd packed tightly on a small dance floor. A nook off to the side of the dance floor offers a place for VIPs to whisper and snuggle. Numerous regular parties keep the action fresh, including something called the Bedroom, which encourages scanty dress and naughty behavior. Expect young ladies in their best sexy gear and guys trying not to look too eager. The space is so elegant, you almost wish for a red rope policy. Roll by dressed to impress on a Friday or Saturday night. Try the mojito or the lemony-sweet Fluid martini.
