In-N-Out Burger Chief Operating Officer Denny Warnick explains the history and variety of the chain's popular off-menu items.
Denny Warnick, the Chief Operating Officer of In-Out Burger, stated that the chain's famous off-menu items, such as the Animal Style burger, originated from customer requests for customized orders. The Animal Style burger, which features a mustard-cooked beef patty, pickles, extra spread, and grilled onions with lettuce and tomato, was first served in the early 1960s.

Warnick noted that many of the chain's named preparations were created by customers who frequently ordered their burgers in specific ways. These variations were eventually given names to describe the preparation of a menu item exactly as a customer wanted it. In-Out Burger, founded by Harry and Esther Snyder in 1948, was California's first drive-thru hamburger stand. The company remains privately owned by the Snyder family and currently operates more than 400 locations in 10 states. Other notable off-menu items include the Double-Meat, the 3x3, the 4x4, the Grilled Cheese, and Protein Style. The Flying Dutchman, created by former CEO Guy Snyder, is also a notable off-menu order.
