where in boston are you staying? how many meals will you need?
i live here and eat out often.
waltham is not "all" that close to boston and you don't need to leave the city to meet your parameters.
for fantastic seafood you can go to island creek oyster bar or neptune oyster. the latter is tiny but i had some amazing crudo there yesterday.
we've also got a vibrant nose-to-tail chef scene here if that is of any interest.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
