We will be spending four days in the Boston suburbs and one full day (Saturday or Sunday) in Boston. We both love seafood but don't know what's fresh in March, where to eat it, and if "fresh" even matters in this age of fresh frozen food. Price is not a concern but we don't want to have to dress up as we'll probably be walking around the city all day. I appreciate any and all suggestions! Do any of the Italian restaurants have great fish and/or lobster?
