We live in Manhattan, but we'll be driving to Cape Cod a few weeks, staying in Hyannis (but we'll drive anywhere in the Cape). We're looking for great, fresh seafood- doesn't have to be fancy. Actually, we like seafood shacks and things like that. Lobster, crab, clam chowder, scallops, shrimp- we're looking for a seafood feast. Any recommendations? We don't want to spend a fortune either.
