It's all good, but I did notice the party is a little thinner, and the tomato is sliced pretty thin, too! Cheeseburger meal and a an additional small soda $11.83.

Food is honestly amazing and despite there always being a long line you very rarely have to wait for more than 5 minutes. The staff seem to always be on top of things, making sure they have the correct order before anything else. Honestly wish there was an in n out closer to where I live but it's still very much worth the

Like every In-N-Out location, this one is just as busy. There is always a huge line here but that’s typical. My coworkers and I picked up some food for a team lunch, a few double doubles, lettuce wrapped cheeseburger and a 4x4. Can’t forget the spread as well. Nice food, In-N-Out never misses!!

Top 30 In-N-Out Secret Menu Items1. Extra ToastThis is for all my fellow toast enthusiasts! Your hamburger bun will be left on the grill for an extra minute or two, making it that much crispier and a whole lot yummier. Yes, it's free of charge.2. Mustard GrilledGuys, this one is no joke. Just say the word and the cook squirts mustard on the top of the patty and flips it, so it literally sizzles and seeps inside the meat *while* on the grill. I mean…3. Cold CheeseIt’s exactly what it sounds like. Sub in the regular melted American cheese with a slice of cold cheese if that’s your thing.4. Double MeatOrder two beef patties but keep the rest of the toppings (tomatoes, lettuce, cheese, etc.) the same for a more meaty experience than your classic Double-Double.5. 3x3 (aka Triple Triple)This burger comes with three beef patties and three slices of American cheese.6. 4x4 (aka Quad Quad)This bad boy contains four (!) beef patties and four (!) slices of American cheese.7. Grilled CheeseThe ultimate vegetarian item on the menu: Ask for two slices of American cheese, lettuce, tomato, spread, and onions on a bun.8. Cheesy WikiJIC a regular grilled cheese isn't enough to happily glue your teeth together: This bb has *four* slices of cheese.9. Protein StyleGluten-sensitive? Just a big fan of romaine? Get your burger wrapped in lettuce instead of a bun.10. Tomato WrapIf you're bored of the infamous "Protein Style", you can get any burger you want wrapped in two slices of tomato instead of bread. Messy, but I am totally here for it.11. Medium RareWith the exception of Nevada (due to state laws), you can ask to get your burger cooked medium rare, if that's your thing.12. Animal Style BurgerThis ~extra~ beef patty is cooked in mustard and comes with extra spread and grilled onions.13. Flying DutchmanAsk for two slices of cheese melted between two burger patties—that’s it. No bun, no greens.14. Wishburger or Veggie BurgerThis sandwich is stuffed only with vegetables—no meat or cheese.15. Chopped ChiliesAdd a sprinkle of hot chopped peppers to the bottom bun for some extra spice.16. Grilled Onions or a Grilled Whole OnionSwap out standard-issue raw onions for sweet and savory caramelized ones.17. Scooby SnackA single grilled beef patty. Y'know, just for a little snack.18. Doggy-StyleA protein-style grilled cheese with fries *inside* the lettuce sandwich.19. Fries Well DoneWant your fries crispier than usual? Simply ask for a batch that spent more time in the fryer. (Soooo worth it.)20. Fries LightOrder lightly-fried potatoes. (UM, I'M JUDGING YOU.)21. Animal Style FriesArguably one of the most popular secret menu items. Top your fries with cheese, spread, and grilled onions. A classique.22. Cheese FriesIf the pile of stuff above isn't your scene, just ask for cheese fries. :)23. Roadkill FriesIf animal-style fries aren't enough for you, order the roadkill fries. AKA, it's a flying dutchman on top of animal fries. Oooooohboy.Advertisement - Continue Reading Below24. Root Beer FloatOrder a half cup of root beer, and ask for a swirl of vanilla shake on top.25. Black and White ShakeAsk for chocolate and vanilla swirled together.26. Neapolitan ShakeOrder three shake flavors (chocolate, vanilla, strawberry) in one cup.27. Around the World ShakeEvery ice cream flavor combined. I mean, sure. Why not?Advertisement - Continue Reading Below28. Lemon UpWe love a good two-in-one deal. And that deal is pink lemonade mixed with 7-Up? Umm, yes please and tysm.29. Pup PattyAn unsalted patty FOR YOUR FLOOFY FRIEND. Brb, sobbing forever.30. 16x16According to the same Reddit AMA mentioned above, staff members are not allowed to make anything larger than a 4x4 anymore. But, I have on record from a native Californian and In-N-Out Expert™ (aka my boyfriend) that the elusive 16x16 still exists out there. I'll let the X-Files theme song play you on your way out.As of 2024 Source Cosmopolitan MagazineVegetarian options: Veggies are a must! Checkout the secret menu items while it's limited it'
