If you're expense accounting, or if you want to put down some of your own money for a great meal in San Francisco, Kokkari is excellent.
When I used to work late a lot and eat dinner at the office, the only restaurant that recognized me was the little Greek grill right across the street. Years after I stopped working there, I walked in and the guy recognized me and made me what I always ordered (verifying it with me, of course, but he still knew).
