Sweet Tomatoes is good, but it's a chain buffet restaurant (just so you know what you're getting into)
They have SPECTACULAR Blueberry muffins and cornbread with honeybutter - great soups (really, really great soups) and pretty good salads. We don't care for the pastas there, but the baked potatoes (over by the soups, usually) are really good.
The golden corral was AWFUL when we went. We also tried an Italian place that was very pretty inside and the food was great, but a little pricey, if I recall.
In all honesty, we try to avoid chains when we go on vacation - anything we can get at home, we don't usually buy out of town. BUT - it does have its place.
There are soooo many restaurants and chain restaurants, especially, to pick from in the area. You'll be hard pressed to not find something reasonable to eat (IHOP, Cracker Barrel, etc).
We also really liked the Taco Bell - the beans they use actually contain REAL beans - seasoned a little spicier than they do up here in the midwest - and we looooved them

I know, goofy - and uber-chain, but it left an impression on me and we found ourselves craving it on our last trip
