Go hungry. Like Claim-Jumper-Level hungry. The food was fantastic, but they give you enough to feed at least two people in every entree.
Went for lunch and had the warm spinach salad. It was good, but I was definitely the odd man out, as all my companions had things like Pot Pie, Corn Beef, Meatloaf, etc. Down home cooking at its finest.
The only thing that kept me from giving it a 5 was that the service was a bit off. All of our entrees arrived sporadically (there was about a five minute gap between the first and last served) and one of the people in my party didn't get the soup they ordered.
Nevertheless, I will definitely go back, and am eager to try something off the breakfast menu.
