WC has an all-you-can-eat bbq skillet for $13.99. It's very good, and it's really all I ever get when I go there. The servers can get a bit silly.
Kona Cafe has a much more relaxed atmosphere, and if you want desserts and coffee after lunch, you will definitely want to dine there. Try the Beef Teryaki Salad.
If you're traveling from MK for lunch, Kona will be the fastest to get to/from.
