Pat's King of Steaks was founded in 1932 when Pat Olivieri prepared the world's first steak sandwich. Olivieri, owner of a hot dog stand, make the sandwich for himself, but when a passing cab driver smelled he tempting aroma of grilling beef he asked for one of the same. Pat sold the cabby his own lunch for two cents and thought little about the incident. But when the cab driver returned with friends Pat's King of Steaks was born. Through the years, Pat's King of Steaks has become a Philadelphia Institution and a favorite haunt of such celebrities as Humphrey Bogart, James Cagney, Frank Sinatra, and Philadelphia's own Bill Cosby, David Brenner, Bobby Rydell, and others. In 1982 to mark the Golden Anniversary of Pat's we proudly opened our Reading Terminal Market location. Since then it's become a Center City lunch tradition and we strive to continue the great Philadelphia steak sandwich Pat established over 50 years ago.
