In-N-Out's Iconic 'Animal Style' Burger Originated from a 1960s Customer Request

Key points

• The 'Animal Style' burger began in the early 1960s after a customer observed an employee making a customized burger and requested the same preparation.
• In-N-Out Burger's Chief Operating Officer Denny Warnick confirmed the name was created on the spot and that many off-menu items originated from customer preferences.
• The chain officially listed these off-menu orders on a 'Not-So-Secret Menu' on its website in 2005.
• The Animal Style burger consists of a mustard-cooked beef patty, hand-leafed lettuce, tomato, pickles, extra spread, and grilled onions.
• In-N-Out remains privately owned by the Snyder family and operates over 400 locations across 10 states, having started as California's first drive-thru hamburger stand in 1948.

Background

In-N-Out Burger was founded by Harry and Esther Snyder in 1948 in a suburb of Los Angeles, establishing the first drive-thru hamburger stand in California. By 1973, the chain had 13 locations, all within Los Angeles County. The company has maintained its private ownership and limited geographic expansion, currently operating in 10 states. The 'Animal Style' order, along with other off-menu items like the 'Protein Style' and 'Flying Dutchman,' became widely known through word-of-mouth and eventually through the company's own online 'Not-So-Secret Menu' in 2005.

Why it matters

The story highlights how customer-driven customization can lead to iconic menu items, even if they are not officially listed. It also illustrates the enduring appeal of In-N-Out's 'secret menu' culture, which has persisted for decades and continues to attract new customers. The company's commitment to fresh-to-order preparation and customer satisfaction has contributed to its reputation and popularity, despite its limited expansion compared to other fast-food chains.

What to watch

In-N-Out Burger is expected to continue serving its off-menu items, including the Animal Style burger, as part of its customer-friendly approach. The company may also continue to update its 'Not-So-Secret Menu' to reflect popular orders. There is no indication of changes to the Animal Style recipe or its availability, as it remains a staple of the chain's off-menu offerings.
