I'm visiting Boston this evening and would appreciate any suggestions for dinner. We're staying at the Parker House and would like to eat around 9:30 or 10:00 pm. I would prefer a restaurant that: (i) won't be upset that I'm not wearing a jacket; (ii) is not too far from our hotel (walk or short cab ride) and (iii) I have a shot at a last minute reservation or which does not take reservations. I'm very flexible on price and cuisine- as long as it's good. Is Radius still good or has it been surpassed? Thanks for your suggestions.
