El Reno, OK 73036

Completing the El Reno trifecta of old-school burger joints, Robert's Grill is a true aficionado of the Oklahoma onion burger. The shambled, undecorated building and basic menu speaks not for the quality of these burgers, where the line between beef and onion is blurred, but it doesn't matter because the line is covered with creamy melted cheese. Nor does it speak for the house-made chili that coats the fresh-cut fries and coneys.
