From the first bite of your burger to your last french fry, quality is the most important ingredient at In-N-Out Burger. Since opening in 1948, we’ve been doing fresh the old-fashioned way. Our burgers are grilled to order made with juicy 100% beef patties and freshly baked buns. We only use crisp, fresh produce, our fries are hand-cut from whole potatoes, and our shakes are made from real ice cream.
Classic burger chain serving customizable burgers, hand-cut fries & shakes.

This In-N-Out location delivers exactly what you’d expect from the brand — fresh ingredients, consistent quality, and that nostalgic California burger experience. The restaurant is clean and bright, with the signature red-and-white decor and a steady flow of customers that keeps the place lively but organized.
The order was the Double-Double with fries and a drink, and it hit the spot. The burger was perfectly assembled — juicy beef patties, melted cheese, crisp lettuce, tomato, and that famous spread that ties it all together. You can tell everything is fresh, from the toasted bun to the crunchy veggies. The fries were hand-cut and lightly salted — simple but classic. A cold drink on the side made the combo complete.
Service here is quick and friendly even during rush hours, and the staff really keep things moving. Prices are super reasonable considering the quality, and the food always tastes fresh, not greasy. Parking is easy, and the drive-thru line, while often long, moves faster than you’d expect.
Overall, this is one of those spots you can always rely on for a great burger done right. It’s not fancy — just pure, honest, California comfort food at its best.

O Lo
You always know exactly what you’re getting at In-N-Out, and that’s the best part. The consistency here is unmatched—the food is always fresh, and the quality of the burgers and fries never dips. On top of that, the service is always top-notch; the staff is quick, friendly, and they run a tight ship even when the drive-thru line is wrapped around the building. It’s easily the most reliable spot for a great meal every single time!

I keep giving this location a try. But to be honest, today was my last straw. Everytime i have ordered a burger there is no lettace, it’s always a little tiny welted piece. Today i ordered the meal with no salt on my fries because if you don’t then they over salt then to the point where they are inedible. I had to go home and add my own lettace because with clear nasty small piece that was in there was gross looking. They didn’t ask me what drink i wanted for my meal so i didn’t get one because i didn’t remember to them by the time i drove off. Its not just this time it’s everytime I’ve been there something is lacking. Sad. Because i love in n out

I was finally able to come to this In N Out location in Simi Valley. My work is in the area but I was closer to In N Out today because I went to take my exam at a testing center near here. I came a little before 10am so I just waited in my car. I know they will start serving guest at 10am but they officially open at 10:30am. I was their first guest today so I was able to put in my 3×2 protein style burger and chopped chilis along with fries. I didn’t know that the person taking my order thought I said a double double until I saw the receipt. I didn’t mind it so I didn’t go correct him. My food didn’t take that long to make and I took it back to the office to eat. The burger is always delicious like always and the fries are basically in n out fries if you know what I mean. The customer service here is excellent and the atmosphere here is great too.

Update: Always a delicious meal! Everything is so tasty and fresh. The service is always amazing! Everyone has a smile on their face. I love sitting inside to eat, as the place always has a room full of really happy people! So glad this place is just a short 0.8 mile walk from my house!

Still the best fast food burger in the country! I like their menu flexibility! Like if you order an Xtra Large Milk Shake it’s in a huge soft drink cup. The fries aren’t as good as KFC fries (the best) or McDonald’s but they’re passable. Double Double Animal Style is an incredible cheeseburger…

My order took an hour to prepare. But in the end, it sat at the register for an hour and no one saw it. I go back every time and ask for my number. They say it’s not ready. And in the end, I got a cold burger with cold fries—that’s just crazy.

This place is SO busy, too busy for the space. Food is no surprise and very consistent from store to store. Every person I’ve dealt with has been professional. The volume is too great. Take over a store in the Simi town center.
