Yes, you can order off of McDonald's "secret menu." But you might be more disappointed in it than you were in the new Hamburglar.

"Don't tell them about the secret menu. Which maybe doesn't exist." (via)

We all like to think that we're cool, in-the-know people, which I think is why we like secret menus at fast food restaurants. It's like you're part of a hip, members-only hamburger club. So when a McDonald's manager from the UK did an AMA on Reddit recently and said that yes, McDonald's does have a secret menu, the Internet erupted with secret-hamburger fantasies. Unfortunately, the menu isn't as cool as you might think:

You can order from the 'Secret Menu'. Just like with any of our sandwiches, you can add, remove or change ingredients by special request. These are called 'grill orders' (i.e. Big Mac no pickle)

The items on the 'secret menu' weren't invented by anyone officially at McDonald's, it's just a random persons guide to burgers you could potentially 'hack' at McDonald's.

Order one and the workers might not know it by name (i.e. Land, Air and Sea burger or the McGangBang) but if you explain what it is, and are willing to pay for all the ingredients, it's just another 'grill order' that we can make up.
