We ordered a hot dog and a hamburger, and we both had fries. We ate in the restaurant. The decor was slightly above Burger King, the service unremarkable, but the food was the worst we have experienced in quite some time.
The burger and hot dog were acceptable (not good), but the fries were actually un-eatable. Since I can usually eat anything, I was surprised to find that I couldn't finish them. They managed to be both greasy and dry at the same time.
I think John Anderson serves Coke drinks, but I'm not sure. We're not going back to find out.
