It's a great concept, and a cute restaurant, but the food is really fast-food at sit-down prices.
I had a burger, and it was incredibly dry (and I never even tasted the cheese). The fries, onion rings, and shakes were great, but given the cost, they better have been!
We tried to sit outside, and the instant we brought our food out, we were absolutely swarmed by flies - so we gave up, and went inside.
