We've talked about different items you can order at fast food joints that aren't actually part of the restaurants official menu. In n Out Burger is probably the most famous with their "animal style" toppings and the 4x4 burger. But there are "secret" items at a bunch of places. McDonald's has the "McGangBand" which is a double cheese burger with a chicken patty in the middle. You can get a pizza sub at Subway. And at Taco Bell they have the Superman Burrito: a cheesy double beef burrito loaded with potatoes, sour cream, guacamole, and tortilla strips. None of these items are on the stores official menu--just the secret menus.

Here's a website that has a ton of other ones from 15 different establishments.
