In-N-Out Secret Menu Orders and How to Ask

Family-owned burger chain from Southern California with a deliberately short menu of burgers, fresh-cut fries, sodas and shakes. It is known for cooking to order and for a set of customizations it openly acknowledges as its 'not so secret' menu.

In-N-Out lists six items on its own Not So Secret Menu page: Animal Style, Protein Style, Double-Meat, 3x3, 4x4 and Grilled Cheese. The 4x4, with four patties and four slices of cheese, is the largest size it lists. Protein Style cuts a Double-Double from 610 to 460 calories.

Quick answer. In-N-Out Burger publishes 6 off-menu orders itself: Animal Style, Protein Style, Double-Meat, 3x3, 4x4 and Grilled Cheese. Ask for them by name when you order.
