Ever since I came across a fake “top secret” menu item, I’ve been looking for a good resource for In-N-Out’s secret menu, partly because I’ve only heard about the menu through word of mouth, and partly because I just don’t know everything my favorite burger joint has to offer. BadMouth ended my search, as they have a pretty good guide complete with mouth watering pictures. Take a look!

A “2×4″ is a burger with two beef patties and four slices of cheese. You can also order a “3×3,” a “4×2″ or any other meat/cheese combo your little heart desires. In the past, we’ve seen burgers as large as a 100×100, but In-N-Out changed their policy and now a 4×4 is as large as you can get.We managed to get ourselves a 20×20before that rule went into effect, though.

A mustard-cooked beef patty with additional pickles, cheese, spread and grilled onions diced up and mixed together on the grill before getting dumped on your burger. This is probably the most famous secret menu item, and for good reason: it’s pure awesome on a bun. You can get any burger done Animal Style.

A cheeseburger without the “burger.” My niece always orders the grilled cheese because she doesn’t eat beef and “veggie burgers are boring.” You still have lettuce, onions and tomatoes — as well as a nice helping of the spread. Can also be ordered Animal Style.

Well damn, now I want In-N-Out. There are plenty more secret menu items to look at, so be sure to head over to BadMouth to check them all out!

Do you know of more secret menu items that aren’t on this list?
