Fat Boy is what it is, an authentic 50's style drive-in, not one built to look like one. The food my not be the best in town, but it's exactly what you would get if you went to a drive-in in the 50's, cheeseburgers, fries, onion rings, frappes. They also have some seafood that is really quite good. I enjoy the lobster rolls, crab meat rolls, fried clam and shrimp dinners.
Pros: Authentic 50's style drive-in experience.
Cons: Lunch and Dinner hours are very busy, so the wait is long.
