Quick Summary

In-N-Out Burger's chief operating officer Denny Warnick credits a customer request in the early 1960s with starting the chain's popular "Animal Style" burger, which features a mustard-cooked beef patty and is listed on the company's "Not-So-Secret Menu". According to Warnick, customers often created their own customized orders, with some names sticking over time. In-N-Out now offers several off-menu options, including Double-Meat, 3x3, and Protein Style, which are available through customer requests. The chain has grown from its first location in Los Angeles in 1948 to over 400 locations in 10 states today.

Story summary

In-N-Out Burger, a fast-food chain known for its simple menu, has a long history of accommodating special orders from customers, which have become popular off-menu items. One such example is the Animal Style burger, which was introduced in the early 1960s after a customer asked for his burger to be made like one of the associates' customized burgers. The name "Animal Style" was created on the spot by an In-N-Out employee, and over time, other variations of menu items have been given names based on customer requests. These off-menu items include the 3x3, which features three beef patties and three slices of American cheese, as well as Double-Meat, 4x4, Grilled Cheese, and Protein Style. According to In-N-Out's chief operating officer, Denny Warnick, the company accommodates special orders because it is "all about making our customers happy." The not-so-secret menu is even listed on In-N-Out's website, including instructions for making an Animal Style burger, which features a mustard-cooked beef patty with hand-leafed lettuce, tomato, and extra spread.
