Besides, check this out:
"One reason In-N-Out has not expanded rapidly is because their food is never frozen. The delivery trucks are only able to travel a limited distance from In-N-Out's sole meat packing plant, where the company does its own boning, grinding, and pattying of fresh beef chuck. Due to logistical and cost issues, it is not likely they will open other meat packing plants. This commitment to freshness has limited the restaurant's expansion to other states in the United States besides Utah, Arizona, Nevada, and California.
In-N-Out focuses on providing a basic menu with few changes since the restaurant was established in 1948.
The simple menu consists of the following:
* Hamburger
* Cheeseburger
* "Double-Double" - a double cheeseburger (two slices of cheese and two meat patties)
* French fries (one size only)
* Milk shakes - chocolate, strawberry, and vanilla.
* Drinks - Coke, Diet Coke, 7 Up, Barq's root beer, Dr Pepper, lemonade, iced tea, milk, coffee, and Root Beer Floats."

Man, personally, that place looks bomb and I want to try their burgers.
LOL. Talk about customization.
