Good martini--inexpensive food in the Back Bay
This might be a Utopian fantasy, but I'm meeting an old friend for dinner in the Back Bay. Neither of us are from Boston, but we'd like a quiet place to drink a few martinis and have a decent, but not outrageously expensive meal (i.e. not Grill 23 or Abe &Louie's). Walking distance to the Arlington train station would be a plus.
