I am taking my mother and my 16 year old son to Boston and we will be staying at the Cambridge Residence Inn. We won't have a car. I am looking for a restaurant close to the hotel for Saturday night because by dinnertime, my mother will probably be very tired from a day of walking. It also has to be a casual dress place (but please no fast food joint!) otherwise my crazy mother will refuse to go. I think everyone is open to just about anything except for heavily fried foods! Have any ideas?
