It seems like there have been some good healthy arguments on this board about seafood restaurants but no discussion yet about places to buy seafood to cook yourself. I'd like to hear people sound off on where they think the best places are.
There's a place on Rt. 2 in Cambridge by the rotaries called Fresh Pond seafood (I think) that I've been to a couple of times and is pretty good. Their tuna was of pretty good quality--not the best I've ever had, but good--and their halibut was great--very flavorful.
