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 is always busy. It is next to a Ross and other stores you can shop at before or after eating.
The food is always consistently delicious and affordable. I have not had an issue with this location.
The employees are nice. On this day (1/27/2026) there was an employee that was taking an extra step to open the door for people coming in or going out. He was consistently acknowledging everyone and making small talk. He was sweeping and came across as a happy person.

Disappointed by the size of burger here after taking it to go from a meeting, then drove home to find it so thin.
Also, did not want to drive back onto the freeway to this location, so called customer support only for them to spell my name and email address incorrectly. I plan to stop eating at In-N-Out.

The interior was designed with their logo pattern, giving it a cleaner and fresher feel. One of the reasons I love In-N-Out is that, unlike other franchises, the taste is the same no matter which branch you go to.

I was in the area for my wife’s cousin’s kid’s birthday party and wasn’t sure what I wanted, so we stopped at In-N-Out on S. Harbor Blvd. I went with a 3×3 hamburger, and having the patty mustard-fried gave it a little extra flavor. I also added grilled onions, but of course, no tomatoes or spread. Service is usually quick here whether you go inside or use the drive-thru. This time, my wife went in and picked up our food. We took it back to the car and ate while it was raining. The ambiance is what you would expect from any In-N-Out, decorated in red, white, and yellow throughout. There is plenty of parking, so that’s not an issue. Next time you’re in the area and feel like grabbing a quick bite, don’t hesitate to stop at this location you won’t regret it.

ALWAYS ALWAYS packed but the service is amazing, coworkers working seamlessly together makes this place function so smoothly, they had an individual (taller, a bit heavier set, glasses) working cleaning the place up, im sad i cant remember his name because he was a GEM!! absolute angel of a person to talk to, food was amazing!

My favourite burger ever and I am so sad that I only get to eat here when I visit family as I live in the UK. Just delicious

I am someone who loves In-N-Out Burger, so I usually feel very excited whenever I go there. However, today my excitement disappeared because of the attitude of the employee who took my order at the drive-thru. While taking my order, he looked like he didn’t want to work, and his manners were not very good. It made me think that better employee training may be needed.

Quite busy at 2 on a Saturday. Picked up a 75th anniversary shirt with my double double meal and strawberry shake. The burger was great as always, the fries have never been my favorite but with some seasoning they are much better. Sat inside because the line for the drive through lane was snaking through the parking lot.

No words to describe In N Out . Everything about this burger joint is 5-star, but you have to find your way through complex maze of parking lot, long drive through lines, and people crossing parking lot haphazardly. If you do all that then you unlock the “In N Out” stage!!

This location is the best In n Out burger.
I have been an In n out customer for over 30 years. This location makes food look like “the picture”. Taste balanced not over salty hell like many other locations. Beautifully assembled components bring joy and satisfaction.
6 out of 5 stars.
