It's a fact that 65 percent of hamburgers are eaten in restaurants. The burgers served at Bricktown Burgers are different from the multitude of Mexican, Asian and deli fast-casual competitors. Mouthwatering burgers come grilled with onions or, if you prefer, without. But don't be foolish. They will add bacon or ham on that burger along with all of the trimmings. So have it your way.
