Steak ‘n Shake bolsters its premium burger lineup with the introduction of the new Frisco Prime Steakburger at participating locations.

The Frisco Prime Steakburger features a 6-oz. hand-crafted Prime Steakburger topped with Swiss and cheddar cheeses, lettuce, tomato and the brand’s classic Frisco sauce on a toasted brioche bun.

The new Prime Steakburger comes served with a side of fries for a suggested price of $7.99 (may vary by location).

Steak ‘n Shake Prime Steakburger patties are made with 100 percent USDA certified beef, using a blend of brisket and chuck.
