This barbecue joint may be located inside a gas station, but that hasn’t kept it from serving up award-winning barbecue that draws long lines. Oklahoma Joe’s has won numerous competitions, including three grand championships at the annual American Royal contest, plus awards for Best Pulled Pork, Best Barbecue Sandwiches, and first place for Mild BBQ Sauce in the 2001 American Royal International Sauce Contest. Customers rave about the “Z-Man,” a brisket sandwich with provolone cheese and an onion ring in the middle.
