In-N-Out Burger products
In-N-Out Burger opened in 1948, providing a basic menu of burgers, fries, and beverages. Unlike other hamburger fast food restaurants, it has not added chicken or salads to its menu since 1976, and has never changed its preparation methods.
The company utilizes vertical integration for its food supplies. The company does not use freezers, instead shipping fresh ingredients daily to each store from its facilities, including potatoes which are cut in each store for french fries. In-N-Out is known for its "secret menu," unadvertised variations of its menu items, such as the popular "Animal Style".
