Southern California-based In-N-Out Burger enjoys cult status. Fans love the juicy burgers, fresh-cut fries, and delicious milkshakes despite the narrow menu and restricted burger toppings.
Anthony Bourdain famously visited In-N-Out, his favourite Los Angeles restaurant, first when he visited.
The chain's "hidden menu" includes a grilled cheese (a cheeseburger without the meat) and "animal style" burgers and fries.
The restaurant's followers have joyfully revealed various ideas to break up the usual online.
Request extra-toasted buns, well-done fries, and mustard-grilled burgers. In-N-Out never disappoints, so have a mustard burger next time.
In-N-normal Out's menu doesn't have mustard. Always ask. The eatery starts a mustard burger with a fresh patty on the griddle.
Only "animal style" sandwiches can be ordered with mustard-grilled patties. Grilled onions, additional sauce, and pickles are added to the same recipe.
Since 1948, In-N-Out has been known for its hamburgers and cheeseburgers.
These classics have a beef patty, iceberg lettuce, tomato slices, raw onions, trademark sauce, and no bacon, mushrooms, avocado, mayo, or mustard.
