Good barbecue is not in short supply in the C-U area. Hickory River is an example of a decent choice when you want BBQ served hot and quick. The restaurant is setup as a cafeteria-style outlet as I've seen in quite a few places in Oklahoma and Texas. This lets them provide fast service at high demand times.
The meats (beef, pork, turkey, sausage) are well-executed and flavorful. Brisket is pretty good and well portioned. There's even a turkey salad available which has the excellent smoked turkey piled high atop a mound of what appears to be Dole salad greens (a little off-putting). The sides are tasty but not particularly notable. Drinks are available from the fountain in the dining area. Overall, the food quality is good and is on par with the price, which is very reasonable.
Although it is a self-service venue, there are bus boys and staff that walk the dining room to check on you and will clear plates from your table when you're done. The service is friendly and fairly attentive despite the cafeteria setup. Hickory River is a favorite of mine when I'm in a hurry and don't want to spend an arm and a leg for barbecue.
