We're trying to think of a nice mid- to high-end restaurant with a private room that would be appropriate for a group holiday dinner. There will be around 18-20 of us, and we are looking for some place in San Francisco, even more preferably in Downtown. Last year, we went to Le Colonial, and it was perfect for our party. Spacious private room with extra lounge seating in addition to the dining tables, as well as a private bar/bartender. We may opt for the same place this year, but I was hoping to get some fabulous new suggestions from the hounds.
