The In-N-Out secret menu is the most famous in fast food — and the least secret. The company itself publishes half of it on a page literally titled “Not-So-Secret Menu,” and the rest is a shared language of order phrases every crew member is trained to understand. This guide lists 23 secret items, styles and customizations with the exact words to say, the typical price, and honest calorie estimates calculated from In-N-Out’s official chart.
Two ground rules before the list. First, unlike most chains, In-N-Out wants you to order these — Animal Style and Protein Style are register keys, not favors. Second, In-N-Out publishes no nutrition for secret items, so every calorie figure marked ≈ is fan-calculated from the official component chart on our In-N-Out menu page. Where a figure IS official (the Protein Style range), it says so.
The Not-So-Secret Menu: In-N-Out’s Own List
Start with the twist: In-N-Out publishes part of its secret menu itself. The company’s website carries a “Not-So-Secret Menu” page listing the Double Meat, 3×3, 4×4, Grilled Cheese, Protein Style and Animal Style — the only secret menu in fast food with an official chapter. Prices for the stacked builds are typical aggregator figures (In-N-Out publishes no prices); the styles themselves are free, because the only add-ons In-N-Out charges for are extra meat and extra cheese.
| Item | How to Order | Typical Price | Calories |
|---|---|---|---|
| Double Meat | Say “Double Meat.” Two patties, lettuce, tomato and spread — no cheese. One of the six items on In-N-Out’s own published not-so-secret menu. | ~ $5.95 | ≈ 540 |
| 3×3 (Triple Triple) | Say “three-by-three.” Three patties and three slices of cheese with the standard toppings. On the official not-so-secret menu. | ~ $8.60 | ≈ 790 |
| 4×4 (Quad Quad) | Say “four-by-four.” Four patties, four cheese slices — the largest build In-N-Out lists, and the cap for stacked orders. | ~ $11.15 | ≈ 970 |
| Grilled Cheese | Say “grilled cheese.” Two slices of melted American cheese on a toasted bun with lettuce, tomato and spread — no patty. Vegetarian by build. | Varies | ≈ 380 |
| Protein Style | Add “protein style” to any burger. The bun is replaced by hand-leafed lettuce. The one style with official nutrition: 210 (Hamburger) to 460 (Double-Double) calories. | Same as base burger | 210–460 (official) |
| Animal Style | Add “animal style” to any burger: the patty is grilled in mustard, with pickles, grilled onions and extra spread. Every added ingredient is a free customization. | Same as base burger | ≈ 710 (Double-Double) |
Register Legends: Flying Dutchman & Friends
These are not on any official page, but every register hand knows them. The Flying Dutchman is the icon — two patties, two cheese slices, nothing else — and the animal fries outsell half the official menu. Calories here are fan-calculated from the official chart, because In-N-Out publishes no secret-menu nutrition; treat them as good estimates, not lab values.
| Item | How to Order | Typical Price | Calories |
|---|---|---|---|
| Flying Dutchman | Say “Flying Dutchman.” Two patties with two slices of cheese melted between them — no bun, no vegetables, nothing else. The keto order, decades before keto. | ~ $6.50 | ≈ 380 |
| Onion-Wrapped Flying Dutchman | A Flying Dutchman with whole grilled onions standing in for the bun: “Flying Dutchman, onion wrapped.” The viral build of the last few years — messy and worth it. | ~ $6.50 | ≈ 400 |
| Animal Style Fries | Say “animal fries.” The one size of fries under two melted cheese slices, spread and grilled onions. The most-ordered secret item in the building. | ~ $5.45 | ≈ 730 |
| Cheese Fries | Say “cheese fries.” Fries under two melted slices of American cheese — animal fries without the onions and spread. | ~ $3.95 | ≈ 500 |
| Wish Burger | Say “wish burger” or “veggie burger.” A toasted bun with spread, lettuce, tomato and onion — the sandwich that wishes it had a patty. Skip the spread and cheese-free build makes it vegan. | Varies | ≈ 275 |
| Pup Patty | A plain, unsalted patty cooked for your dog. Fan sources widely report it as free; it is not officially published, so ask at the counter and expect a small charge at worst. | Reported free | ≈ 110 |
Free Customizations: The Order Words
The deepest layer of the secret menu costs nothing at all. In-N-Out charges only for extra meat and extra cheese, so doneness, onions, chilies, mustard-grilling and spread packets are free vocabulary. Learn these phrases and you can rebuild any burger on the board without spending a cent more.
| Item | How to Order | Typical Price | Calories |
|---|---|---|---|
| Fries, Your Way | One size, five doneness levels: “fries light,” “light-well,” regular, “well done” or “extra well done.” Well-done is the regulars’ fix for fresh-cut fries’ natural softness. | No extra cost | — |
| Whole Grilled Onion | Ask for a “whole grilled onion” — a full slice grilled until sweet, instead of the standard chopped raw onion. It takes a few extra minutes on the grill. | No extra cost | — |
| Chopped Chilies | Say “with chopped chilies” — fresh Cascabella peppers, chopped and scattered on the burger or fries. The menu’s hidden heat. | No extra cost | — |
| Mustard-Grilled Patty | The Animal Style cooking method without the toppings: “mustard-grilled.” The patty fries in mustard for a tangy crust. | No extra cost | — |
| Spread Packets on the Side | Ask for extra spread packets — the same 1948 sauce, in dipping form, for fries or a second burger. Free on request. | No extra cost | — |
| Mustard & Ketchup Swap | Order any burger “with mustard and ketchup instead of spread.” An official order style that cuts exactly 60 calories from every burger on the official chart. | No extra cost | −60 (official) |
Secret Drinks & Shake Blends
The shake machine holds three flavors, which means it secretly holds at least six: the Neapolitan layer, the black-and-white swirl and any two-flavor mix, plus a root beer float if you ask kindly. At the fountain, the Arnold Palmer and Lemon-Up are self-serve traditions. Shake prices are the standard shake price — the blends are free.
| Item | How to Order | Typical Price | Calories |
|---|---|---|---|
| Neapolitan Shake | Say “Neapolitan shake.” All three flavors — chocolate, vanilla, strawberry — layered in one 15 oz cup. Order it at the counter; there is no button for it, but every crew knows it. | $3.45 | ≈ 600 |
| Black & White Shake | Chocolate and vanilla swirled: “black and white shake.” Any two-flavor mix works the same way. | $3.45 | ≈ 600 |
| Root Beer Float | A vanilla shake floated with Barq’s root beer. Per long-running ordering guides, associates will mix it for you if you ask at the counter. | $3.45 | ≈ 590 |
| Arnold Palmer (“Tea Ade”) | Self-serve at the fountain: about 60% pink lemonade over 40% unsweetened iced tea. The lemonade carries the calories; the tea keeps it honest. | $2.25 | ≈ 120 |
| Lemon-Up | 80% pink lemonade, 20% 7UP, self-serve. Brighter and fizzier than the straight lemonade. | $2.25 | ≈ 170 |
In-N-Out Secret Menu Allergen Information
Secret styles rearrange the same small set of ingredients, so the allergen logic is simple: the bun carries wheat, egg, sesame and soy; cheese adds milk; the spread contains egg; and the shakes are milk (plus soy in the chocolate). Protein Style removes the bun entirely — the gluten-free route — while the Flying Dutchman (patty and cheese only) avoids wheat, egg and sesame altogether, keeping milk and soy from the cheese. In-N-Out restaurants use no peanuts, tree nuts, fish or shellfish, but shared grills and prep areas mean cross-contact is always possible. The full table is on the main menu page.
In-N-Out Secret Menu Nutrition
There is no official panel for a single secret item, so this page calculates from the official chart’s components — and shows its work. A beef patty works out to about 110 calories, a cheese slice about 70, the bun about 150 (that is exactly what Protein Style saves), the spread about 60–80, and grilled onions roughly 20–40. Stack them and the famous numbers fall out: a 4×4 is the 610-calorie Double-Double plus two more patty-and-cheese pairs (≈970), and animal fries are the 360-calorie fries plus cheese and spread (≈730). The one set of official secret-adjacent figures is Protein Style, published on the chart itself: 210, 280 and 460 calories across the three burgers. Our In-N-Out nutrition page has the full official chart.
In-N-Out Opening and Closing Hours
Secret items are available whenever the kitchen is — there is no secret-menu window. Most restaurants open at 10:30 AM and close at 1:00 AM (1:30 AM on Friday and Saturday), and the late-night drive-thru is when the Flying Dutchman orders peak.
| Day | Typical Opening | Typical Closing |
|---|---|---|
| Monday to Thursday | 10:30 AM | 1:00 AM |
| Friday | 10:30 AM | 1:30 AM |
| Saturday | 10:30 AM | 1:30 AM |
| Sunday | 10:30 AM | 1:00 AM |
| Drive-thru | Same hours | Two lanes at most stores |
In-N-Out Reviews: The Original Baldwin Park Restaurant
The secret menu was born at stores like the Baldwin Park original — 13850 Francisquito Avenue, beside the 1948 site — where regulars’ orders became the culture. It holds a 4.7 out of 5 rating from about 3,400 Google reviews (as of 2026). The reviews below are real Google reviews of that restaurant.
“This restaurant is very good both for the food and for the price. Very tasty flavors, attentive service.”
— Ian Man Matsunaga, Google review (5 stars)
“One of my favorite In-N-Out spots because the merch store is on same lot. I got a double double protein style animal wrap with fries and a medium drink. Of course it was delicious, the burger was phenomenal and the fries were on point.”
— Rodrigo, Google review

In-N-Out Secret Menu Facts
- In-N-Out is the only major chain that publishes part of its own secret menu — the ‘Not-So-Secret Menu’ page on its official website.
- Animal Style began as a surfer-era regulars’ order in the 1960s; the name came from the rowdy young customers who ordered it, staff folklore says.
- The 4×4 is the largest build on the official not-so-secret list — In-N-Out stopped making the legendary 100×100 (a 2003 catering stunt) and anything beyond four patties is not a register order.
- Protein Style predates the low-carb craze by decades: lettuce-wrapped burgers were a quiet menu option long before they were published.
- The Flying Dutchman’s name is a wink at the ghost ship — a burger that appears with nothing around it: no bun, no vegetables, just meat and cheese.
- In-N-Out charges for only two customizations in the whole system: extra meat and extra cheese. Everything else in this guide is free.
- A whole grilled onion takes around nine minutes on the grill — order it when you walk in, not at the window.
- Chopped chilies are fresh Cascabella peppers, the same peppers served whole in the little packets by the ketchup pump.
- The spread recipe has been unchanged since 1948 — and packets of it are free for the asking.
- Cut-in-half is an official courtesy: any burger can be halved or quartered for kids and sharing, free.
- The Roadkill Fries and Monkey Style burgers of internet fame are not register items — order animal fries and a Flying Dutchman and assemble them yourself.
- Secret-menu fluency is part of training: new associates learn the styles because the register has keys for most of them.
In-N-Out Secret Menu FAQs
Does In-N-Out really have a secret menu?
Yes — and it is only half secret. In-N-Out publishes six items itself on its official ‘Not-So-Secret Menu’ page (Double Meat, 3×3, 4×4, Grilled Cheese, Protein Style, Animal Style). The rest — Flying Dutchman, animal fries, the free customizations — are register-recognized traditions the crews are trained on.
How do you order Animal Style at In-N-Out?
Just say ‘animal style’ with any burger or fries. On a burger it means a mustard-grilled patty, pickles, grilled onions and extra spread; on fries it means two cheese slices, spread and grilled onions melted over the top. The burger version costs nothing extra; animal fries run about $5.45.
What is a Flying Dutchman at In-N-Out?
Two beef patties with two slices of American cheese melted between them — no bun, no lettuce, no tomato, no sauce. About $6.50 and roughly 380 calories by component math. The onion-wrapped version swaps in whole grilled onions as the ‘bun.’
What is the biggest burger you can order at In-N-Out?
The 4×4 (Quad Quad): four patties and four cheese slices, about $11.15 and ≈970 calories calculated. It is the largest build on the official not-so-secret menu; larger stacks are not register orders.
Is Protein Style actually healthier?
It is the one style with official numbers: wrapping in lettuce saves exactly 150 calories and about 30 g of carbs on every burger (Double-Double: 610 → 460). Sodium also drops by about 280 mg. The trade is structural — a lettuce wrap is a two-handed commitment.
Can you still order a 100×100 at In-N-Out?
No. The 100-patty stunt burger was a one-off catering spectacle in the early 2000s, not an orderable item. The register tops out at the 4×4; for a crowd, order several 4x4s and extra patties on the side.
Conclusion
Learning the In-N-Out secret menu is learning the chain itself: a handful of ingredients, endlessly recombined, most of it free. Master the phrases on this page, start with a Double-Double Animal Style and fries well done, and you will order like a Baldwin Park regular. The components and their prices are on the full In-N-Out menu, the official numbers are in our nutrition chart, and the savings logic — in a chain with no coupons at all — is on the coupons and deals page.
