The word "steak” stood for STEAKBURGER. The term "shake” stood for hand-dipped MILK SHAKES. Gus was determined to serve his customers the finest burgers and shakes in the business. To prove his point that his burgers were exceptionally prime, he would wheel in a barrel of steaks (including round, sirloin, and T-bones) and grind the meat into burgers right in front of the guests. Hence arose the origin of our famous slogan, "In Sight It Must Be Right.” After 79 years, we are continuing Steak n Shake's tradition of serving the country's best, freshest, and tastiest burgers and shakes.
