I am going to be honest, I am a bit of a snob when it comes to food but I am trying to keep on a budget these days of under $20 per person for a meal. Any hidden finds that have a nice atmosphere, neighborhood joints? I live in Back Bay so I can easily go to Kenmore, Beacon Hill or South End. Reasonable drinks/wine list is another plus! I moved from Manhattan recently so I am bummed by the lack of BYO in Boston proper. Any ideas much appreciated!
