The fast food chain Steak 'n Shake, which last year switched from vegetable oil to beef tallow to cook fries, is making more moves under newly appointed Chief MAHA Officer Michael Boes to go "back to the glory days of fast food." They claim it won't raise their prices. "Fortunately, we operate as a private entity, and so we believe if we do right by the customers, the market's going to reward us," he said.
