Bite of History

Folklore has it, the cheeseburger was invented in 1924 when a California teenager, Lionel Sternberger, got innovative at his father’s restaurant. He topped a slice of American cheese to a hamburger, tasted it, and instantly the cheeseburger was born.

Over the years, the love for this cheesy classic has flourished. As per the U.S. Department of Agriculture, Americans now consume nearly 50 billion burgers each year.

Why Celebrate?
