Use of the term "steakburger" dates to the 1920s in the United States. In the U.S. in 1934, A.H. "Gus" Belt, the founder of Steak 'n Shake, devised a higher-quality hamburger and offered it as a "steakburger" to customers at the company's first location in Normal, Illinois. This burger used a combination of ground meat from the strip portion of T-bone steak and sirloin steak in its preparation. Steak burgers are a primary menu item at Steak 'n Shake restaurants, and the company's registered trademarks included "original steakburger" and "famous for steakburgers". Steak 'n Shake's "Prime Steakburgers" are now made of choice grade brisket and chuck.
