Origin of the Philadelphia cheesesteak (Pat's King of Steaks)

The cheesesteak is widely credited to Pat Olivieri, who in the early 1930s began selling chopped beef sandwiches in South Philadelphia and later opened Pat's King of Steaks. Pat's has operated at the same corner in South Philadelphia since its founding and is commonly cited in historical accounts as the birthplace of the sandwich. The restaurant continues to serve the classic steak-and-roll preparation that established the local food tradition.
