5 Guys!!! I try to eat there every time the wife and I come up to Ft Smith. Is usually a toss up between them and Braum's. Braum's would have to be my favorite chain hands down. They produce all their own food and are one of the greatest examples of vertical integration. Unless you live with in 300 miles of Tuttle, OK, they won't open a store in your town. It's an ice cream and dairy store that milks their own cows and has fantabulous burgers!
