I need some recommendations in San Fran. We'll be arriving Xmas eve and staying through til the 29th. I'm not so worried about the other days, but am concerned about the 24th & 25th. What are some good places to eat that are open on those days besides Chinatown and the hotel restaurant? We'll be staying in Nob Hill and will be getting around on public transportation. I'm open to everything, my husband and I are very adventurous eaters.
