I am going to be in San Francisco for one day only this weekend and am looking for a suggestion for Sunday night. I will be with one friend, possibly two, and we are all lovers of food. Quality is the most important factor, but a good ambiance is always appreciated. I am also somewhat of a food adventurer; always looking for the new and exciting. Almost no limitations; except for Mexican food ( I live in L.A. and there is no point eating it anywhere else but Mexico!). Any ideas or suggestions would be great. Or, just listing your own personal favorites. Thanks!
