This Tybee Island favorite is causal by day and romantic by night. Located in a nondescript shopping center about one block from the beach, Sundae Cafe features an extensive lunch menu, with everything from island-inspired spicy tuna tacos and fried oysters to more traditional fare such as club sandwiches, chicken fingers and burgers. At night, the restaurant transforms into an elegant cafe with a superb selection of appetizers and entrees, including the seafood cheesecake appetizer--a decadent mixture of shrimp, lump crab and smoked gouda in a garlic butter crust--and a sweet potato-crusted grouper entree that incorporates shrimp beignets, peach and cranberry chutney, fried sweet potato shoestrings and wilted spinach. Desserts, which are displayed in a glass case at the front of the cafe, are equally mouthwatering and run the gamut from key lime pie to Reese's Peanut Butter pie.
