In Rockport, naturally, seafood holds center stage. And this informal restaurant knows how to cook it. The clam chowder is really excellent, as is the fish sandwich, made with a freshly-fried slab of halibut. Lobster macaroni and cheese is the best version of this you're likely to find anywhere, and the lobster BLT is one of the greatest sandwiches you can eat anywhere--assuming you like lobster. Even the grilled sourdough bread they make the sandwich with is outstanding.
