We're relatively new to town and are taking an out-of-town friend out for a birthday dinner. We were thinking of places like Gary Danko or Boulevard (which we haven't yet tried) but were wondering if you have favorites in a slightly lower price range (20s, as opposed to 30s for entrees) -- with a similar sense of ambiance and elegance and good service. We'll be a group of 6 or 8 and would love a place with comfortable booths or tables and where the volume is such that we can talk. Type of cuisine is flexible. We can dine anywhere in the city although easy access to BART or Muni for all parties would be a plus. Thanks for any help on this.
