Although I live in San Francisco, where XYZ is located, I recently had to work across the street at Moscone Convention Center for over a week and dined at XYZ twice daily. As a member of the Starwood Preferred Guest Program, the bonus was two fold, earning points in the program and enjoying fresh and innovative meals. Though I have my favorite dishes there, I did try a number of meals during the lunch period and agree with RupertS that XYZ is worth a visit. The staff is friendly and mostly attentive and the food is better than most hotel restaurants I've dined in.
