Come on, face it. Sometimes you just want to to be a part of the in-crowd. And being in-the-know on what's cool, unique and special can help you get there.

We're here to help when it comes to food. So the next time you're getting lunch with co-workers, or dinner with a friend, impress them with your knowledge of these special, off-the-menu items.

This list is far from complete. GrubStreet made a list of more high-end secret menu items in 2012 and Hackthemenu.com has many more.

We will also continue to update this story with more off-the-wall (and off-the-menu, duh) items as we find them!

Shake Shack's ShackMeister

The item: ShackMeister cheeseburger. UPDATE: This special menu

The item: ShackMeister cheeseburger. UPDATE: This special menu item is no-longer secret! It's available for a limited-time at all U.S. Shake Shack locations!

Where you can get it: All Shake Shack locations

The details:The ShackMeister is a brand new item from Shake Shack, the rapidly expanding and hugely popular New York City-based burger brand. The cheeseburger, which won a recent SOBE Wine and Food Festival Burger Bash, is a cheeseburger topped with ShackSauce (secret recipe, but it's mayo based and is both sour from pickles and spicy from spices) and crispy ShackMeister Ale-marinated shallots. The ShackMeister Ale is made by the Brooklyn Brewery.

Shake Shack loves off-the-menu items (perhaps you've had the grilled cheese made on a Martin's potato roll?), and likes to live by the "if we can make it, we will" principle.

"Our guests love to customize their food," said Mark Rosati, Culinary Director for Shake Shack, adding that if they have the ingredients, they will make it happen.

Where you can get it: All Chipotle locations

The details: The Quesarito is hugely popular and pictures and testimonials can be found all over the internet. It's exactly what it sounds like, a burrito wrapped in a quesadilla instead of just a plain old tortilla. Double the tortillas, double the fun, right? And you can never go wrong with more cheese. This bad boy is said to pack a whopping 1,500-calorie punch.

Subway's Pizza Sub

The item: The Pizza Sub Where you can

The item: The Pizza Sub

Where you can get it: All Subway locations

The details: According to Hackthemenu, the Pizza Sub was briefly on the Subway official menu, but is still available off-menu. Thank goodness, because this one is especially fun. While many of the "new" Subway creations are a little too adventurous for our tastes, the Pizza Sub couldn't be simpler: it's made with pepperoni, cheese and tomato sauce. And then, like with any other sub from Subway, you can add your choice of veggies. Simple and straight-forward.

The item: The Grand Slam Where you can

The item: The Grand Slam

Where you can get it: Wendy's

The details:Enjoy the Grand Slam at Wendy's when you're just having one of those days, and one or two burger patties WON'T CUT IT. While this item typically consists of four patties, (get it, grand slam, four bases), apparently you can add on as many as you want, if that's your thing! But something tells us you might not make it back to work after...
