Dear Mr. XXXXX:
Thank you for your e-mail, and for your interest in In-N-Out Burger.
In response to your question, we have several commonly requested burger styles, such as Animal style which do not appear on our menu. A you may know, our Animal style burgers come with lettuce, tomato, extra spread, pickles, grilled onions, and mustard fried into the patty. We also offer Protein style burgers, for which we wrap the burger in large leaves of lettuce instead of placing it on a bun.
In addition, we have commonly requested burgers that are not on our menu. These burgers include the Wish burger, the Grilled Cheese burger, the Double-Meat, and the 3x3. The Wish burger is similar to a hamburger but does not contain the meat. The Grilled Cheese burger is similar to the Wish burger, but adds two slices of melted cheese. The Double-Meat is similar to the Double-Double in that it has two meat patties, but it does not have cheese. The 3x3 burger is a burger with three meat patties and three slices of cheese, and you can add meat patties and slices of cheese to make a 4x4, 5x5, etc.
Again, although these styles and burgers are not on the menu, you can order them at all our locations.
Thank you again for contacting us.
Sincerely, Customer Service Representative
There is a website if people want to know the full secret menu. I have to say, I am impressed with their philosophy and website. I just assumed they were another unimpressive Fast Food outfit. (Never having eaten there, but having seen friends eat the stuff.)
