Dave’s Grill deserves its reputation as one of the best restaurants around. Its waterfront setting affords views of Montauk Harbor with the coming and going of the Viking Fleet and local charter boats. Reservations are same-day, phone-only from 4:15 p.m. The inventive menu includes Dave’s signature cioppino, and popular dishes include onion and potato-crusted flounder and grilled lobster on a baked brioche. Appetizers might be Vietnamese Peekytoe crab and mango salad or smoked tuna spread with warm pita triangles and crudite. The Chocolate Bag, filled with vanilla ice cream and raspberry compote, is hard to resist. There’s a full bar and eclectic wine list, and indoor or al fresco dining.
