Fast food isn’t just about convenience—it’s about indulgence, creativity, and, sometimes, a dash of culinary rebellion. For those in the know, secret menus offer a thrilling way to customize orders and experience flavors beyond the standard fare. From mammoth burgers to whimsical desserts, these menu hacks could turn ordinary meals into legendary experiences.
To that effect, here are 10 off-menu creations that will take your fast-food experience to the next level:
Grilled Cheese Cheeseburger (Five Guys)

Why choose between two classics when you can have both? This popular, secret menu item sandwiches a juicy cheeseburger between two grilled cheese buns. It’s the culinary equivalent of a bear hug – messy, comforting, and slightly excessive.
Coined the “Grilled Cheese Cheeseburger,” the menu item typically uses a single burger bun turned inside out and grilled to resemble grilled cheese, holding together a juicy cheeseburger patty loaded with toppings of your choice. While not officially on the menu, you can order it by requesting a grilled cheese with a burger patty added.
The Incredible Hulk (Taco Bell)

Taco Bell takes its 5-Layer Burrito to superhero status with The Incredible Hulk, which swaps out nacho cheese sauce for creamy guacamole. The result is a fresh and flavorful twist on a fan favorite that feels lighter but still packs plenty of punch.
For an even healthier option, you can order this secret menu item in the Fresco style to replace sour cream with pico de gallo, a type of Mexican salsa that is dairy-free.
Land, Air & Sea Burger (McDonald’s)

McDonald’s unofficial trifecta of patties combines a Big Mac (land), McChicken (air), and Filet-O-Fish (sea) into one absurd sandwich. The result? A flavor tsunami that’s equal parts ridiculous and delicious. Warning: May require two hands and a side of regret.
This creative concoction, born from customer ingenuity rather than corporate planning, has gained quite a following on social media and through word-of-mouth. While you’ll need to assemble this epic mashup of the three iconic sandwiches yourself by ordering each sandwich separately, many fans argue that the end result is worth the effort.
The Meat Cube (Wendy’s)

If you think Wendy’s Dave’s Single is satisfying, wait until you meet “The Meat Cube.” This secret menu item, which also goes by the name “Grand Slam,” is a towering stack of four-quarter-pound beef patties layered with cheese, lettuce, tomato, and any other toppings like onions and other condiments you might want.
It’s a meat lover’s dream and a true test of your appetite. Just ask for a burger with four patties on a bun with your preferred toppings — no decoder ring required, and bada bing bada boom! Roll up your sleeves and tackle that meaty masterpiece.
BK Surf & Turf (Burger King)

Burger King’s Surf & Turf is a secret menu creation that combines two fan favorites: a beef burger and a fish sandwich. It’s an option worth considering if you’re bored by the usual burger choices and are willing to explore beyond the standard menu.
This gourmet mashup layers a flame-grilled beef patty with a crispy fish filet, topped with lettuce, tartar sauce, and other classic toppings.
You can order the secret menu item in two ways: request a Big Fish with a Whopper patty added (for fish sandwich fixings), or ask for a Whopper with a fish filet added (for Whopper toppings), or you can order the items separately and assemble them yourself if you fancy the DIY experience. It’s worth noting that the King’s Surf & Turf availability and staff familiarity may vary by location.
Midnight Truffle Blizzard (Dairy Queen)

For chocolate lovers, Dairy Queen’s Midnight Truffle Blizzard is an indulgent off-menu delight that combines their signature vanilla soft-serve with rich chocolate truffle pieces and cocoa fudge.
Though not officially on the menu anymore (the treat was a regular “Blizzard of the Month” menu item between 2009 and 2015), many locations will still whip it up on request. It’s a rich, velvety upgrade to the classic Blizzard – perfect for when you want to feel fancy while wearing sweatpants or satisfying late-night cravings.
Suicide Burger (Burger King)

For those with a truly hearty appetite, Burger King’s secret menu offers the outrageous Suicide Burger. This monstrous creation features four beef patties, four slices of cheese, bacon, and a special sauce, all sandwiched between a sesame seed bun (in some locations, at least).
It’s a protein-packed powerhouse that lives up to its dramatic name. To order this off-menu item, simply ask for the Suicide Burger by name or request a Quad Stacker with added bacon and special sauce.
If you’re a fast food enthusiast looking to push the boundaries of conventional offerings and indulge in a truly epic meal, this burger is for you. For the full secret menu experience, consider pairing it with Frings – a side that’s half fries and half onion rings. Depending on the location, you can get this secret menu item for anywhere between $3.99 to $6.59.
Flying Dutchman (In-N-Out)

For those on a keto diet or anyone who simply loves enjoying the meat minus the carbs, In-N-Out offers the Flying Dutchman, an off-menu favorite that skips not just the bun but the veggies, too! What you’re left with are two perfectly cooked beef patties embracing two slices of melted American cheese.
It’s pure meaty bliss in its most minimalist form—and if you’re feeling bold, you can order it “Animal Style,” where staff will add diced onions to the cheese with pickles and spread on the side for an extra kick of flavor. The Flying Dutchman is typically priced at $5.
Butterbeer Frappuccino (Starbucks)

Harry Potter fans can bring a little magic into their day with Starbucks’ secret menu item — the Butterbeer Frappuccino. This charming drink mixes a Vanilla Crème Frappuccino base with caramel syrup and toffee nut syrup for a sweet, buttery flavor reminiscent of J.K. Rowling’s famous wizarding drink.
Pro tip: Ask for caramel drizzle on top for that authentic Three Broomsticks experience. Accio caffeine!
Artery Annihilator (Five Guys)

Five Guys is known for its customizable burgers, but if you’re feeling adventurous (and hungry), try the Artery Annihilator. Not for the faint of heart, this burger hack is the combination of a classic bacon cheeseburger with a half-hot dog placed on top of it.
It’s over-the-top in the best way possible and delivers an explosion of smoky, savory flavors. Just ask for a bacon cheeseburger and request a split hot dog added to the mix, and you will have yourself the Artery Annihilator — or you can even order the burger by name in some locations and watch the magic happen.
