If you’re in the food business, a secret recipe can mean the difference between fortune and bankruptcy. At KFC headquarters in Louisville, Kentucky, for example, Colonel Sanders’ original recipe sits on a shelf in the chain’s legal department. Meanwhile, Coca-Cola hid the formula in a storage room at the World of Cola Coke in Atlanta. (Fans can access the Vault but cannot view the recipes.)
And then there’s Popeyes Louisiana Kitchen, the chicken chain that is removing its Super Bowl ad for the first time this year.
