Secret fast food

Now of course I knew about the In N Out secret menu, although do they really cook the animal-style patties in mustard? If so, Rob's never been able to taste it when he orders his that way.

But here's a slideshow of other fast fooderies' secret menus. I dare you to go to McDonald's and order a Neapolitan shake! Apparently it's a shake that's squirted into the cup by thirds--one-third strawberry, one-third vanilla, and one-third chocolate.

The Meat Cube from Wendy's, however, is just nasty.
