$25 Gift Card Steak'n Shake.

The chain's name was derived from the two principal menu items: burgers made—then, as now—from ground round, sirloin, and T-bone; and hand-dipped milkshakes.

Three quarters of a century later the chain has more than 500 locations in 22 states and continues to serve burgers using the "smash" technique, which dates back to the origins of the hamburger itself.
