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.

Nothing beats In-N-Out! When you got the urge for that double double with cheese this spot will get you in and out. The service is efficient and friendly. My wife and I shared fries animal style, not really my favorite. My burger was perfect. We sat in the seating area here very nice, very clean.

I was surprised by my experience today.
I understand that mistakes can happen, but my order was misunderstood and the receipt was split into two, which was already confusing.
More concerning was that a donation was added to my bill without my consent or any prior explanation, apparently to make the change even.
The issue is not the amount, but the principle. Adding a donation without explicit customer authorization raises serious consumer-rights concerns and is not an acceptable business practice.
Donations must always be clearly disclosed and strictly optional.
Additionally, I specifically requested no salt on my French fries, yet I was served fries that were not fresh and were salted regardless.
I also found it uncomfortable that staff members were carrying beverage containers through the ordering counter area, interrupting customers mid-order and forcing them to step aside. This reflects poor operational flow and customer consideration.
Overall, this experience felt disorganized and lacked transparency. I hope management reviews these practices to ensure clearer communication and respect for customer consent.

I am not generally a “burger” person however we were hungry! I have to say without question this was so amazing and tasty. It was succulent, juicy and I was blown away!! Can’t believe I have been won over. Would so recommend this.

Last night around 5:30 PM, I declined the donation at the drive-thru line, yet I was still charged for it. I only noticed after reviewing my receipt once I left. This is unacceptable and needs to be addressed

I have been eating at in & out since I was a young child. It’s quite a nostalgic place for my family and I. It has always been one of the only fast food places that I know will have great customer service as well as quality food. I’m giving a 2 star review only because I was shocked by my experience yesterday evening at the diamond bar location. My family and I walked up to the window to order take out. The ordering process was great, kind young kid took our order, however, what surprised me and compelled me to leave a 2 STAR review was Because When our order was ready, one of the female employees put the bag of fries on the counter to complete the order, the bag tipped over on the front counter and the fries spilled out of the bag onto the counter, she then grabbed the fries with her hand off the counter and threw them back in the bag. I thought for sure she was going to toss the bag in the trash and get me a new order but NOPE, the male kid just handed me over the bag. I was so shocked, I was actually speechless. I think what through me off the most was that I did NOT expect this from IN&OUT. The company holds their employees to a higher standard than all other fast food places. I’m only writing this review In hopes that leadership can make sure to continue to hold this franchise to a higher standard and not let this type of service continue. In and out is the only fast food place left that is constant in their customer service and food quality.

I have no complaints other than please do not throw my napkins into my literal food. I cant use the napkin if its covered in food.

I went at 11:30. The fries were definitely old fries that had been rewarmed, mixed in with fresh fries. It’s a distinctive taste. Very very disappointing.
The burgers are getting smaller.
Again, very disappointed with the quality.

When in LA! My wife kept telling me how good In-N-Out was and after trying it for myself, I totally agree! I also tried the vanilla shake and wow it was amazing!

Used to not be a big fan of in n out
But after living here awhile and comparing to other fast food.
I can say that their burger are fresh and tasty , also the fries.
I like the cheese fries too, not the animal fries.
Also like their shakes a lot, its a real shake, not like smoothie.

The service is wonderful. Staffs are very charming and helpful. They talk to you respectfully and they take your order in details. They have great smiles and make you feel valuable. Food tastes as great as any In-and-out does. This location only has drive through and take-out, no inside seating.
