I usually lunch with a Prater's BBQ sandwich and tea - straight back from the What, paired with some fries from a nearby vendor. My go-to dinner is the chicken tenders and fries from the vendor that is always set up stage right at What, sort of in front of the VIP hill. They do it right. Pair that with a lemonade from the pizza folks next door and I'm set.
Spicy Pie, Outback Kate's, and Bearly Edible are also staples. My wife pretty much eats ONLY Pesto Mozzadilla while we're there. I have been eating their grilled cheese for 12 years so i usually go with that. Grilled cheese and cold Mountain Dew before a late night...oh hell yes.
