If you love burgers, you might already know that In-N-Out has some of the best in the business. But did you know they also have a secret menu with some incredible options?

One of the most popular is the Animal Style Burger, which includes mustard-grilled beef patties, extra spread, grilled onions, and pickles, giving it a bold and flavorful twist. For those looking for a lighter option, the Protein Style Burger replaces the bun with fresh lettuce, making it a great low-carb choice.

Another must-try is the Flying Dutchman, which consists of two beef patties and melted cheese without a bun, offering a simple yet delicious way to enjoy pure beef and cheese.
