If you want the quesorito at Chipotle, just ask. They will probably make it if they aren't slammed. Wait, did you mean our cars? They have a secret menu too?

Well, it's a little bit of a devil. Ever play Google Seppuku? It's when you do a Google image search using a random Japanese word or phrase you copied from a Japanese language site, with all the search filters off. Then you see how many pages you can go before you see something that makes you want to kill yourself. This is potentially a VERY NSFW venture.
Clearly i was only thinking of burgers when you said " Hidden Menu " Glad someone was able to keep a clear head.
