You're standing at the counter of a crowded In-N-Out in Hollywood, or maybe a drive-thru in a dusty corner of Arizona. The air smells like toasted buns and grilled onions. You’ve seen the TikToks. You’ve seen the grainy Instagram photos of a burger piled so high with fried sides that it looks more like a structural engineering project than a meal. You want to order the In-N-Out Gorilla Style burger.
Stop right there.
If you actually say those words to the person behind the register, you’re probably going to get a blank stare. Or a polite smile that says, "I have no idea what you're talking about, please just order a Double-Double."
The reality of the In-N-Out Gorilla Style burger is a weird mix of internet mythology, "hack" culture, and the very strict operational reality of one of America's most beloved fast-food chains. People love a secret. They love feeling like they have a backstage pass to a menu that isn't printed on the wall. But there's a massive difference between "Animal Style"—which is a legitimate, internal company standard—and the chaotic energy of the Gorilla Style rumors.
What is In-N-Out Gorilla Style supposed to be?
In the world of food bloggers and viral "menu hacks," the In-N-Out Gorilla Style burger is allegedly a burger (usually a Double-Double) topped with a literal mountain of Animal Style fries right inside the bun.
Think about that for a second. You have the beef, the cheese, the spread, the grilled onions, and then you shove an entire boat of fries—also covered in cheese and spread—into the burger. It's a carb-on-carb masterpiece that sounds like something a college student invented at 2:00 AM.
The rumor mill suggests that "Gorilla Style" is the secret code word to get this done for you. But here is the cold, hard truth: In-N-Out associates are generally not allowed to put fries inside your burger. It violates their strict assembly standards. They are trained to make burgers a very specific way to ensure quality and food safety.
Honestly, the "Gorilla Style" name probably comes from the sheer size and messiness of the concept. It's primal. It's aggressive. It’s also completely unofficial. If you want this, you're going to have to be your own chef.

The legend of the secret menu vs. reality
In-N-Out is famous for its "Not-So-Secret Menu." This isn't just marketing; it’s a list of modifications that the POS (Point of Sale) system actually supports. When you order a 4x4 or Grilled Cheese, the cashier hits a specific button.
- Animal Style: The most famous one. Mustard-cooked beef patties, extra spread, and grilled onions.
- Protein Style: The burger wrapped in lettuce instead of a bun.
- Flying Dutchman: Two patties and two slices of cheese. No bun, no veggies.
- Chopped Chilies: You can ask them to add yellow cascabella peppers to any burger.
Notice what’s missing? Anything involving fries inside a burger.
The In-N-Out Gorilla Style doesn't exist in the company's training manual. I've spoken with former employees who worked the "board" (the station where burgers are assembled). They’ve told me that while they can customize a lot of things—like "extra toast" on the bun or "cold cheese" instead of melted—the moment you ask them to handle a different menu item and merge it with a burger, the system breaks down. It creates a mess, slows down the line, and frankly, doesn't meet the visual standards the Snyder family has maintained for decades.
Why do people keep talking about it?
Social media is a powerful drug. A few years ago, a series of videos went viral claiming that "Gorilla Style" was the new "Animal Style." It’s the classic "one weird trick" that people love to share.
But there’s a nuance here. Sometimes, if you find a particularly chill associate during a slow shift, and you ask them nicely to put some fries on your burger, they might do it. This "exception to the rule" is what fuels the fire. One person gets it done, posts a photo, and suddenly thousands of people think it's an official menu item.
It’s not.
Most of the photos you see of a In-N-Out Gorilla Style burger are actually DIY jobs. People buy a burger, buy a side of Animal Style fries, and do the assembly at their table. Honestly, that’s the better way to do it anyway. You control the fry-to-beef ratio. You don’t make the cashier’s life difficult. You get the same result without the awkwardness of being told "no."

The logistics of a DIY Gorilla Style burger
If you're going to commit to this caloric odyssey, you need to do it right. You can't just toss some cold fries on a burger and call it a day.
First, you need a solid foundation. A 3x3 (Triple Triple) is usually too much height. A Double-Double is the sweet spot. Order it Animal Style with extra spread on the side. This is crucial because the fries are going to soak up a lot of moisture. You need that extra spread to keep things lubricated.
Then, order your Animal Style fries "well done."
Standard In-N-Out fries can get soggy pretty fast, especially when they’re buried under cheese and onions. If you get them well done, they provide a much-needed crunch. Once you have both items, find a seat. Take the top bun off. Use a fork to layer the cheesy, oniony fries onto the patties. Press the bun back down firmly.
There. You’ve just created a In-N-Out Gorilla Style burger. It’s glorious. It’s also probably about 1,200 calories.
Real talk: Is it actually good?
This is where opinions diverge. Some people swear by the texture of fries in a burger—it's a very "Pittsburgh" move, similar to what Primanti Bros. does. The salty crunch of the potato against the savory beef is a classic combo.
However, many In-N-Out purists hate this. They argue that the bread-to-meat ratio is already perfect. Adding fries just makes the whole thing a mushy, starchy mess. You lose the nuance of the fresh lettuce and the snap of the tomato.

I’ve tried it. It’s a "one and done" experience. It’s fun for the novelty, but you quickly realize why the experts at In-N-Out haven't put it on the menu. It's heavy. Really heavy. You’ll probably want a nap immediately after.
Comparing the "Gorilla" to other regional hacks
In-N-Out isn't the only place with these weird urban legends.
- McDonald’s Land, Air, and Sea: A Big Mac, a McChicken, and a Filet-O-Fish all shoved together.
- Five Guys "Patty Melt": Asking for a grilled cheese and adding burger patties to it.
- Shake Shack "Shandy": Half lemonade, half beer (which they actually will do for you in some locations).
The difference is that some of these are easier for the kitchen to execute. The In-N-Out Gorilla Style requires a level of "cross-contamination" between the fry station and the burger board that most managers just won't allow. In-N-Out is a machine. They value speed and consistency over viral trends.
What you should actually say to the cashier
If you want to experience the flavors of a In-N-Out Gorilla Style without the social anxiety, just follow this script:
- "Can I get a Double-Double Animal Style, please?"
- "Can I also get an order of Animal Style fries, made well done?"
- "And could I get two packets of spread on the side?"
That’s it. You’ve ordered everything you need. No "secret code" required. No confused looks. You pay your ten bucks, you get your tray, and you head to your table to build your masterpiece.
Actionable insights for your next visit
If you’re dead set on trying the In-N-Out Gorilla Style or any other major "hack," keep these tips in mind to ensure you actually get what you want:
- Go during off-peak hours: If the line is out the door, the staff will be much less likely to entertain "weird" requests. Try 3:00 PM on a Tuesday.
- Don't call it Gorilla Style: Use descriptive terms. Ask for what you want (fries on the burger) rather than using a nickname they might not know.
- Be prepared for a "No": If they say they can't do it, don't argue. It's likely a company policy or a food safety rule.
- The "Secret" is in the modifications: You can ask for your onions to be "whole grilled" instead of chopped. You can ask for your bun to be "un-toasted." You can ask for a "Lemon Up" (lemonade and 7-Up). These are real things that the staff actually knows how to make.
- Bring your own napkins: If you successfully assemble a Gorilla Style burger, you are going to need a lot of them.
The In-N-Out Gorilla Style is a testament to how much we love to play with our food. It's a fun, messy, and slightly ridiculous way to experience a classic brand. Just don't expect the person wearing the paper hat to know the secret password. The secret is that there is no secret—just you, a burger, a tray of fries, and a dream.
To make the most of your next trip, try ordering your fries "well done" regardless of whether you’re putting them on a burger. It’s the single best way to upgrade the In-N-Out experience, as it solves the "soggy fry" problem that has plagued the chain for years. Pair that with a burger that has "chopped chilies" and you’ve got a meal that’s actually better than any viral hack you'll find on the internet.
