If you have ever been to In'N'Out you know what "Animal Style" means. If not then here is a little info for you. You can go to In'N'Out and order a cheeseburger or french fries just like any other fast food establishment. But you can also order it "Animal Style" which will get whatever you order smothered in their secret sauce, cheese, and caramelized onions. It is the "Animal Style" french fries that inspired this Animal Style Potato Salad.
