Boat Drinks - a must stop for broiled jumbo shrimp and oysters where the St. Croix meets old Miss. On Yelp, I couldn't locate this establishment tucked "under" The Pilot House called "Boat Drinks", but you can enter Boat Drinks through The Pilot House on Main street in Prescott. Or street/riverside in the back.
Go down the basement for the most wonderful broiled jumbo shrimp (1.50 each), oysters on the half shell or baked, and cheese bread. Pizza on the menu too. A must stop for snacks and beverage if on the river or on the river road.
