My boyfriend and I will be in San Francisco next week, and I am looking for new restaurants for us to try. We are staying in Union Square, with no car, so places that are easily accessible by the bart are probably best. This is our third "eating" trip to SF, so we have been to a lot of the usual places (Zuni, Tartine, Incanto, Contigo, La Taquieria, Dim Sum, etc.) We are open to any price range, but I would really like to find some great hole in the wall places also. We aren't picky about food style and will try most anything. Any recommendations are appreciated. Thanks!
