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 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 butter poached lobster on a warm brioche. Local fish specials change daily. Appetizers might be clams casino, chopped salad, honey hoisin Chinese spare ribs 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.
