Options are limited but the seafood is as fresh as it gets — you are eating what was in the water this morning. Lobster, clams, and scallops from Passamaquoddy Bay are the standouts. The waterfront has a handful of restaurants ranging from casual chowder houses to slightly more ambitious kitchens. In summer the demand from visitors fills tables quickly; reservations are a good idea at the better spots. In the off-season, some places close or operate reduced hours — check before you go.
