We just ate at tusker house last week. My hubby and I both had the grilled chilled chicken salad with foccaccia bread and my son had a "fried" chicken sandwich which was very good. The only problem was for our 7 yo picky DD; the only 2 kids' options are pbj (which she doesn't eat) and mac n cheese--which she wouldn't eat because it had "fat" macaroni as opposed to the Kraft narrow macaroni with the powdered cheese which is one of her 3 food items.
They let me purchase some of the corn chowder separately, which was very good (I know, because she wouldn't eat it) and we gave her some of our salad and chicken, which she did eat.
Another option would be Donald's breakfast o saurus, right at closing, which would give you a very late breakfast, although perhaps more food options than you'd like. It works out well in a touring schedule, because it gives you time to go to Africa for the safari, see ITTBAG, then go get a fastpass for Dinosaur and eat at donald's while you wait.
