Does In and Out not have a kids' menu? I've looked at their menu on their website and it appears they do not. We will be stopping there for lunch on our way down (never been before) but have 4 kids with us. Anyone know?
They don't. They have 3 things:
Burgers
Fries
Shakes/malts
It's true they have a very limited but highly customizable menu that can be scaled for adults or kids. For example, an adult might order a double double (2 patties + 2 pieces of cheese), which would come with lettuce, tomatoes, onions, and spread (like french dressing). For our kids, we usually order a plain cheeseburger (which would come as 1 patty + 1 cheese, no veggies or mustard, ketchup, or spread). Sometimes the kids might get a grilled cheese, which is just the cheese, no patty between the bun.
You can order the burger any size you like, i.e. 3X3 (3 patties/cheese), 3x4, 4x4, etc. I believe there is some sort of maximum (4x6 maybe?) instituted after people started getting into triple digits. Another popular option is "animal style", where the patty is grilled in mustard, onions are grilled instead of fresh, and comes with extra spread and pickles.
My personal choice these days is the double double with grilled onions (instead of fresh) and hot chiles, sauce on the side.
Other variations include "protein style" (no bun), or "veggie" (no meat but with everything else). You can also get the fries "well done" (extra crispy), "light" (soft), or "animal style" with cheese, onions, and spread on top.
They also serve coke products, lemonade, iced tea, and milk.
