My 15yo son and I will be visiting downtown Boston next week. We are interested in sampling so of the restaurants and other food places that you local hounds are proud that it's in your city. Some of the places we would like to sample are pizza restaurants and joints (warning--I lived in NYC for many years and consider myself a pizza maven), ice cream places, burger restaurants, and anything else that you really like.(fish, red sauce Italian, etc.) We would prefer to stay away from the tourist places. Healthy is a plus.
