We like the Hungry Bear. We normally grab lunch there at least once during out trip. I've got to go against the grain for the time being about Red Rocketts though. We weren't impressed. I didn't think the pizza was very good (bit of a pizza snob) and I honestly don't care for pasta. I'm thinking maybe we'll give it a second chance on our next trip though.
When we want a quick, easy lunch, we grab a corn dog. It's always filling, we can usually find a seat on a bench under the tree by the first aid station, and there's usually some sort of entertainment going on in the general area.
