California cult favorite serving simple menu done perfectly. Fresh-never-frozen patties, secret menu, and legendary customer service.
In-N-Out Burger was founded in 1948 in Baldwin Park, California by Harry and Esther Snyder, making it one of the oldest burger chains on the West Coast and the first drive-through hamburger stand in California. Now headquartered in Irvine, California, the company remains entirely family-owned and privately held, a distinction that has allowed it to maintain quality standards and a deliberately limited menu that many larger chains cannot sustain. The menu consists of hamburgers, cheeseburgers, Double-Doubles, fries, shakes, and soft drinks — plus a set of unofficial 'secret menu' items that have become as famous as the official offerings. Animal Style modifies the chosen burger to add extra spread, grilled onions, and mustard cooked into the patty; Animal Style Fries replaces plain fries with a layer of cheese, grilled onions, and spread; and Protein Style wraps the burger in lettuce for guests avoiding bread. All beef is fresh, never frozen, and delivered daily to locations; potatoes are hand-cut in each restaurant from whole Russets. The combination of straightforward execution, fresh ingredients, and prices well below the fast-casual premium market has built an intensely loyal following across California, Nevada, Arizona, Utah, Texas, Oregon, Colorado, and beyond. The chain expands slowly and deliberately, and locations in states without In-N-Out are considered by regular visitors a notable absence. The interior design — clean white-and-red tiles, palm tree murals at flagship locations, and the arched yellow sign — has become an immediately recognizable California aesthetic emblem.

Highlights
- Double-Double: two patties, two slices of cheese, lettuce, tomato, and the house spread on a toasted bun
- Animal Style — mustard-grilled patty, extra spread, and grilled onions — the most beloved secret menu modification
- Fresh, never-frozen beef patties and hand-cut fries from whole Russet potatoes, prepared in-store daily
- Family-owned since 1948 and deliberately private — quality and pricing consistency that franchise expansion rarely achieves
- Iconic West Coast identity: the yellow arched sign and red-tile interiors are as recognizable as the food
Tips for visiting
- Order Animal Style on any burger for the grilled onion, mustard-seared patty upgrade — it is not on the regular menu board but is universally known
- Fries are best consumed immediately; Animal Style fries with cheese and spread justify the extra cost
- Drive-through lines move faster than they appear; the kitchen is efficient and orders are made to order
- Protein Style (lettuce wrap instead of bun) is a genuine option for those avoiding gluten or bread
- Shakes are hand-spun from real ice cream; the chocolate shake is a solid companion to a Double-Double
Accessibility

Frequently asked questions
What is Animal Style at In-N-Out Burger?
Animal Style is the most famous item on In-N-Out's unofficial 'secret menu.' It modifies a burger to include mustard cooked into the patty during grilling, extra Thousand Island-style spread, pickles, and grilled caramelized onions. Applied to fries, it adds cheese, spread, and grilled onions.
Is In-N-Out Burger only in California?
No. In-N-Out now operates in California, Nevada, Arizona, Utah, Texas, Oregon, Colorado, and Idaho. The chain expands slowly and deliberately; locations are concentrated on the West Coast and Southwest.
Why does In-N-Out Burger have a cult following?
The combination of fresh, never-frozen beef, hand-cut fries, a clean and simple menu, consistently low prices, and excellent customer service — all maintained by a family-owned company that does not franchise — has produced a loyalty that larger chains rarely sustain.
Is there a vegetarian option at In-N-Out?
The Grilled Cheese is In-N-Out's vegetarian burger: two slices of American cheese with all standard toppings and spread on a toasted bun. French fries are cooked in a dedicated fryer using sunflower oil. The menu is not designed for vegans.
Does In-N-Out have a full secret menu?
In-N-Out acknowledges and accommodates several off-menu preparations including Animal Style, Protein Style (lettuce wrap), 3x3 and 4x4 burgers (extra patties and cheese), Flying Dutchman (two patties and two slices of cheese only), and Neapolitan shakes (strawberry, chocolate, and vanilla combined).
