I moved to San Francisco just 2 weeks ago from Washington, D.C. While I have enjoyed the restaurants I've been to so far, this city strikes me as an early-to-bed dining scene. It seems that almost all the restaurants here close at 9:30 or 10 pm, even on the weekends. I am tired of being turned away from restaurants when I stumble in at 9:45. Can you give me any suggestions for restaurants in San Francisco that close late -- say, 1 am -- even on week-nights? Thank you.
