Is the In and Out Secret Menu Really a Secret?

Not exactly. Most “secret menu” items are custom orders built from ingredients already in every In-N-Out kitchen. Animal Style, Protein Style, and size builds like 3×3 and 4×4 have become so widely known that associates recognize them immediately by name.

In-N-Out’s own trademark records include terms like 2×2, 3×3, 4×4, and 5×5 — which confirms these aren’t random internet inventions. Other names like Gorilla Style or Roadkill are community-created terms that may or may not be recognized by name depending on the location.

The practical difference: well-known items can be ordered by name. Lesser-known combinations should be described by their ingredients.

Secret Burgers — Core Items

Animal Style

The most widely ordered off-menu item at In-N-Out. The patty is cooked with mustard directly on the grill — it creates a tangy, slightly crispy crust on the beef. Toppings added: extra spread, caramelized grilled onions, and pickles.

Available on any burger. The Double-Double Animal Style is the most common combination.

Protein Style

The bun is replaced with a large iceberg lettuce wrap. Same patties, same toppings, same spread — just no bread. Makes any burger a lower-carb option. Check In-N-Out’s official nutrition page for the exact carb count on your specific build.

Available on every burger including 3×3, 4×4, and Animal Style.

Flying Dutchman

Two beef patties with two slices of American cheese melted between them. No bun, no toppings, no spread. Popular with customers looking for a bun-free, lower-carb burger option.

3×3 and 4×4

Three or four beef patties with matching cheese slices — same toppings as a Double-Double. Both are In-N-Out trademark terms, not internet inventions.

A 5×5 is also part of In-N-Out’s trademark records. Whether it’s prepared at a specific location depends on the associate and manager — ask politely if you want to try.

2×2 — What It Means

A 2×2 is simply another way of describing the Double-Double build — two patties, two cheese slices. It’s an In-N-Out trademark term. You can order it either way and get the same burger.

Double Meat

Two beef patties with no cheese. Standard toppings. For customers who want more beef without the extra cheese.

How to order: “Double Meat” or “two patties, no cheese”

Mustard Grilled

Just the mustard-grilled patty technique from Animal Style — without the grilled onions, extra spread, or pickles. Adds a tangy note to the beef without the full Animal Style build.

How to order: “Can I get my patty mustard grilled?”

Secret Fries

Animal Style Fries

Regular fries topped with melted American cheese, caramelized grilled onions, and In-N-Out spread. The most recognized secret fries combination. Eat immediately — the toppings soften the fries within minutes. Order well done first for better texture under toppings.

How to order: “Animal Style fries”

Cheese Fries

Regular fries with melted American cheese on top. Simpler than Animal Style — no grilled onions, no spread.

How to order: “Fries with cheese”

Well Done & Light Well Fries

Both cost the same as regular fries. Well done means crispier, more golden. Light well means softer, less color. Most useful fry customization after Animal Style.

How to order: “Fries well done” or “light well fries”

Secret Drinks & Shakes

Neapolitan Shake

All three shake flavors — chocolate, strawberry, and vanilla — blended together in one cup. Costs the same as a regular shake. A popular off-menu shake combination at In-N-Out. See the shakes page for full shake details.

How to order: “Neapolitan Shake”

Black & White Shake

Half vanilla, half chocolate blended together. Same price as a regular shake.

How to order: “Black and White Shake”

Root Beer Float

Vanilla shake base combined with Barq’s Root Beer. Slightly higher than a regular shake price. Availability may vary — describe it if the associate is unsure.

How to order: “Root Beer Float”

Arnold Palmer

Half unsweetened iced tea, half lemonade. A simple low-calorie combination available at any location.

How to order: “Arnold Palmer” or “half iced tea, half lemonade”

In and Out Customizations & Free Add-Ons

These are available at no extra charge on any order:

See the allergen menu page for full ingredient details on any of these customizations.

Community-Created Names — Order by Describing Ingredients

Some names commonly associated with In-N-Out online are not widely standardized terms. If you want one of these combinations, describing the ingredients is more reliable than using the nickname:

Community NameWhat to Say Instead
Gorilla Style“Double-Double with Animal Style fries inside the burger”
Roadkill Burger“Double-Double with a crumbled patty mixed into the toppings”
Roadkill Fries“Animal Style fries with a crumbled burger patty on top”
Wish Burger“Hamburger, no meat, no cheese”
Scooby Snack“One plain patty, no salt, no bun”
Monkey StyleSame as Gorilla Style — describe the build

These combinations can be made at most locations. The issue is that the nicknames aren’t universally recognized. Describing what you want takes five extra words and removes any confusion.

How to Order at the Counter and Drive-Thru

Well-known items — just say the name:

  • “Double-Double Animal Style”
  • “Cheeseburger Protein Style”
  • “4×4”
  • “Animal Style fries”
  • “Neapolitan Shake”

Community names — describe the build:

  • “Can I get a Double-Double with Animal Style fries stuffed inside?”
  • “Fries with a crumbled patty on top, Animal Style”

Free customizations — add at the end:

  • “Double-Double Animal Style, add chopped chilis, grilled onions on the side”

At the drive-thru: Same process as the counter. Common secret menu orders go through smoothly. For less familiar combinations, describe the ingredients rather than using a nickname — it’s faster and avoids confusion.
