3X3 and 4X4

What is the secret? Two burgers that put In-N-Out’s Double Double to shame.
Where can you order this? At any In-N-Out location.
Best time to order: Lunch or dinner (or both?).

Why we love it: If In-N-Out’s Double Double simply isn’t cutting it for you, then the burger you need to be ordering is the 3X3 or the 4X4. It’s pretty self-explanatory. These burgers include either three or four juice meat patties instead of two (as well as lettuce, tomato, and cheese). Our advice? Don’t jump into the 4X4 without giving the 3X3 a shot, first. Because if you can’t handle three patties, four will be overwhelming.

And for dessert…

Neapolitan Milkshake

What is the secret? A three flavor milkshake.
Where can you order this? At any In-N-Out location.
Best time to order: To accompany your lunch or as a snack.

Why we love it: Want the best of all three worlds? We thought so. At In-N-Out, you can order the Neapolitan Milkshake, which consists of vanilla, strawberry, and chocolate. The best part is that, since you’re not requesting a larger size (unless you want to), the price of this shakes is the same as a regular shake. And if you’re not feeling like trying all three flavors at the same time, ask for two!
