Fast food chains are known for their speed and consistency—but behind the official menus lie some of the most interesting, flavor-packed items you won’t see advertised. These “secret menu” creations are often built from existing ingredients, giving loyal fans and savvy diners access to hidden gems. Here’s a guide to fast food secret menu items you can actually request, plus how to order them without confusing the kitchen.
- In-N-Out – Animal Style Everything
In-N-Out is arguably the king of the secret menu. Their “Animal Style” upgrade includes grilled onions, extra spread, and mustard-grilled patties.
Order it on:
- Burgers: Ask for an “Animal Style Double-Double”
- Fries: Ask for “Animal Style Fries” to get cheese, spread, and grilled onions
Bonus: You can also order a “4×4” (four patties, four cheese slices) or go bunless with a “Protein Style” burger.
- Starbucks – Pink Drink with Matcha Cold Foam
While not a fast food chain in the traditional sense, Starbucks has one of the most customizable menus.
Try this secret item:
- Pink Drink with vanilla sweet cream cold foam and a scoop of matcha
- Order through the app by customizing a Pink Drink base
Other well-known secret menu options include the Butterbeer Frappuccino and the Medicine Ball (Honey Citrus Mint Tea), which became so popular it was added to the official menu.
- McDonald’s – Land, Sea, and Air Burger
McDonald’s once promoted this build-your-own behemoth online. It combines a Big Mac, Filet-O-Fish, and McChicken into one stacked sandwich.
How to order:
- Buy the three sandwiches separately
- Combine them yourself, or ask staff politely to build it if they’re familiar with the request
Other hidden favorites:
- Apple Pie McFlurry (if the machine is working, of course)
- Poor Man’s Big Mac (a McDouble with Big Mac sauce and shredded lettuce)
- Chick-fil-A – Buffalo Chicken Mac & Cheese
Chick-fil-A fans have developed hacks like the Buffalo Chicken Mac & Cheese, which involves:
- A side of Mac & Cheese
- Grilled or spicy chicken nuggets
- Zesty Buffalo Sauce
Simply order all components separately and mix them together—or ask if your local location will prep it for you.
- Taco Bell – The Incredible Hulk Burrito
Taco Bell has one of the most flexible menus around, making secret combos easy to build.
The “Incredible Hulk” is a fresco-style 5-Layer Burrito with guacamole swapped in for nacho cheese.
Other options include:
- The “Cheesarito” – cheese, sauce, and scallions in a warm tortilla
- The “Double Grilled Quesadilla” – just ask for it grilled twice for extra crisp
- Sonic – Purple Sprite
Sonic Drive-In is famous for its drink customization. One of the most-requested secret combos is the Purple Sprite.
How to order:
- Sprite + Powerade + lemonade + cranberry juice
The result is a sweet-tart, candy-like soda hybrid that’s popular with Sonic fans nationwide.
- Arby’s – Meat Mountain
The Meat Mountain is legendary. While no longer promoted, many Arby’s locations still honor this over-the-top item if you ask for it.
It includes:
- Chicken tenders, roast beef, brisket, turkey, ham, corned beef, and bacon
- Plus cheddar and Swiss cheese
It costs more than a typical sandwich but is big enough to feed two.
How to Order Secret Menu Items Like a Pro
- Be polite and clear. Not every employee will be trained on off-menu items, so explain what you want using menu ingredients.
- Order during slower hours. Customizations are more likely to be accepted when lines aren’t wrapped around the block.
- Use apps when possible. Some chains (like Starbucks or Taco Bell) allow detailed customization through their mobile ordering systems.
Final Thoughts
Secret menu items are a fun way to break out of the fast food routine—and when you know how to order them correctly, they’re totally accessible. From Animal Style fries to Purple Sprite, these hidden gems prove that your next drive-thru order can be anything but ordinary.
