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.

What else can I say but it’s a typical In n Out experience. All the employees are super nice and helpful. Spotless floors and condiment/drink stations. Super fast finishing each order despite always being packed.

In-N-Out always hits the spot. Great prices, fresh ingredients, and super customizable — the #1 combo is my go-to. It gets packed, so finding a table can take a minute, but it’s worth it. My kids love the plain burgers, and the buns are always perfectly toasted. Thinking of asking for extra toasty next time!

My visit to In-N-Out burger at this location was not pleasant. First of all the wait time was ridiculous for such a small order. 18 minutes?? Oh c’mon this is not acceptable for a fast food chain. Second of all, the burger patty was flavorless and dry. Bread bun was stale and hard, and the lettuce did NOT taste fresh. Third of all the milkshake was straight up waste of money, no consistency in the strawberry flavor whatsoever and it’s so runny as if it’s literally just melted “strawberry” ice cream. Overall I wasn’t satisfied with the quality as my stomach began to hurt 10 mins after consuming the food. This location specifically has let me down with its flaws. In conclusion, will not be visiting again. Other locations are much better with their shakes as well as the juiciness of the patties. What a letdown.

In N Out is a MUST HAVE for anyone visiting Cali! I’ve definitely missed it since moving out of state. It was my families first stop for food once our plane landed.
Their customer service is always top notch and wait times typically aren’t too bad. They’re good at keeping the line moving if you go through the drive thru.
Highly recommend trying their animal style fries! It’s not on the menu but definitely an item you won’t regret ordering!

Grew up in SoCal and moved out of state 11 years ago so it’s been a LOOOOOOONG time since I’ve had some In-N-Out. Always hear that it’s the best thing in Cali and a must have for anyone visiting. In all honestly the food was indeed very good but I can’t say it’s the best thing in Cali. I will say that the food is priced very affordably and doesn’t break the bank like all other fast food restaurants. So if you’re looking for a bite to eat that won’t break the bank and enjoy some amazing sit down atmosphere I would highly recommend.

This is the first time not giving a five star review to any In-N-Out Burger I visited. The food was great the restaurant was clean but something about the service was off. First when they were taking our order a person seemed not interested and didn’t really listen to my request when I asked if we could get our milkshakes at the end or if they had to give them to us at the same time with our meal. Not a huge deal but he just wasn’t wanting to listen. Then they messed up our order and when I went back to tell them she kind of looked at me like she didn’t believe me and it took her about a minute to decide what to do. I told her I could bring her the tray If she didn’t believe me. She finally said OK we’ll just make you a new one. But it took over 12 minutes to get it. People that were in line waiting to order received their full meals before I received my replacement burger. Other than that everything else is great including the food as always.

I had the double-double, fries and a chocolate shake. Love the food. More importantly, I love that they include Bible references on their products. Mine has Nahum 1:7 on the burger wrapper: “The LORD is good, a stronghold in the day of trouble; he knows those who take refuge in him.” I also had Proverbs 24:16 on my fries, “For the righteous falls seven times and rises again, but the wicked stumble in times of calamity.” And I had Proverbs 3:5 on my drink cup, “
Trust in the LORD with all your heart, and do not lean on your own understanding.”. Great food and great words in one place. I love that!
