I realize, by default, I am biased but I think the food at Dollywood is awesome.
Dick and his folks at Knoebels have the best valued food in the industry. When you can get two NY style Pizza slices and a large drink for five bucks that is a great value. You throw in ice cream on a waffle for two bucks and you are VERY full for the price of a value meal at Wendy's.
All that said, Dollywood's classic skillet taters or freid green tomatoes in the fall are amazing. Everyday, you can get TRUE Southern food at Dollywood at Aunt Granny's or Granny Ogle's Ham and Beans. They still serve fried baloney!
The BBQ is award winning and the Backstage Restaurant was nominated for a Grammy about 10 years ago - yes, a Grammy for its catered foods for the visiting artists.
If you have not tried the food at Dollywood you should. The presentation alone in the big skillets are awesome.
