Dock House, owned by Andrea Shastid and Rob Gettling, is right on the wharf in Sag Harbor and a great place to eat in or take out fresh seafood. Watching boats go by while eating one of its many seafood dishes is a plus. Grilled platters with spicy shrimp, tuna, swordfish, or scallops, with a choice of french fries or salad, are well-priced and ample. You might try the award-winning clam chowder, Manhattan or New England, both great.
