This is a hamburger stand with major attitude. It's open only in the summer, and there's no address, no sign, no phone! Go for the juicy burgers, crispy at the edges and topped with onions fried until they're caramel sweet. Eat in your car or at a picnic table tucked into a leafy grove by the side of the road. Locals and summer people alike know about Clamp's so just look for lots of cars and a line at the order window.
