I'll be taking my wife for her birthday to Boston for five nights in a few weeks. We are staying at Copley Square and we love to walk (except in sleet, but cold does not bother us). Can anyone suggest two or three nice places for dinner. I would prefer no tie but I do wear jackets (I can wear a tie if the restaurant is worth the effort:-)). We have no preference in foods. It can be American, Italian, Greek, seafood or not. We like a nice ambiance and good food and wine. All advice is appreciated.
