The premier fine-dining spot in Sandwich, located in the Belfry Inn, the Belfry Bistro also gets an A for atmosphere. The setting is a converted church: You enter through a majestic arched doorway, and once inside you see the raised floor where the altar used to be and plenty of pretty stained glass windows. This is a roomy space, so couples will find it a good spot; no chance of a neighboring table eavesdropping. The chef takes his cues from the season, revising ingredients to feature the freshest local and regional ingredients. Start the meal with a lovely slow-roasted beet salad or chilled Wellfleet oysters. Main courses include a small but quality selection in the areas of fish, poultry, and meat, be it spring lamb loin with sheep’s milk yogurt or day-boat sea scallops with Madras curry.
