It's not really more items- but rather different ways of ordering the menu items available. For example, you can order your burger "animal style" and you will get a burger that's been cooked with mustard, and loaded with extra sauce, pickles and grilled onions. See: http://www.badmouth.net/in-n-outs-secret-menu/ http://www.tiburon-belvedere.com/cgi/home.cgi?c=In_N_Out http://www.rajuabju.com/literature/innoutmenu.htm

"3-by-3" = three meat patties and three slices of cheese. "4-by-4" = four meat patties and four slices of cheese. "2-by-4" = two meat patties and four slices of cheese. *Note: You can get a burger with as many meat patties or cheese slices as you want. Just tell the In-N-Out Burger cashier how many meat patties and how much cheese you want and that is what you'll get! For instance, if you want 6 pieces of meat and 10 pieces of cheese tell them you want a "6-by-10." "Double Meat" = like a Double Double without cheese. "3 by Meat" = three meat patties and no cheese. "Animal Style" = the meat is cooked and fried with mustard and then pickles are added, extra spread and grilled onions are added. "Animal Style Fries" = fries with cheese, spread, grilled onions and pickles (if you ask for them). "Protein Style" = for all you low-carbohydrate dieters, this is a burger with no bun (wrapped in lettuce). "Flying Dutchman" = two meat patties, two slices of melted cheese and nothing else - not even a bun! Fries "Well-Done" = extra crispy fries . . . even better than the regular! Fries "Light" = opposite of fries well-done, more raw than most people like 'em "Grilled Cheese" = no meat, just melted cheese, tomato, lettuce and spread on a bun. "Veggie Burger" = burger without the patty or cheese. Sometimes we call this the "Wish Burger." "Neapolitan" Shake = strawberry, vanilla and chocolate blended together.
