W Hotels are notorious nationwide for their über-hip bar scenes and San Francisco's XYZ is no exception. Silver-beaded doors open up into a long rectangular room dominated by an illuminated bar that changes color every few seconds. This is pricey to maintain, so the mixed drinks aren't cheap. Excellent mojitos, the house specialty, go for $10. The crowd is the see-and-be-seen set more associated with Los Angeles than San Francisco. Insiders don their blackest black outfit, keep a cell phone pinned to their ear, pretend to be important and fit right in. friend and I went here for drinks and chatting. It was perfect, we got there before any club kids so it wasn't crowded until later. You do have to go outside the hotel to smoke, which was a little annoying - but the waitress was nice to make sure we still has our spots when we came back. The martini's were great. The bathrooms were clean. The seats were comfy. You couldn't ask for more. Yeah, the drinks are about $10, but just get one with a lot of alcohol and soon you won't care!
