"Quaker Steak & Lube is a casual dining restaurant chain based in Sharon, Pennsylvania. The original restaurant was built in 1974 by George "Jig" Warren and Gary "Mo" Meszaros in an abandoned gas station in downtown Sharon, and decorated with license plates and old automobiles. Originally a "cook-your-own-steak" establishment, Quaker Steak's signature dish is now its chicken wings and the variety of sauces used to season them. The name is a play on that of the motor oil company Quaker State."
