This spot has become one of my favorite stops during any drive. Getting in and out is simple, and the food comes out fast every time. The burgers taste just as good as ever and the fries have that perfect mix of crunch and soft warmth. It is also a relaxing place to take a short break before getting back on the road. There is plenty of shade, lots of open space, and our little terrier Rufus loves wandering along the grassy areas while we stretch out for a moment.

“Thanks, Tyler, from the Night Shift”
I don’t usually write reviews, but tonight felt… different.
I stopped by the Jack in the Box around 1:30 a.m. You know the one — tucked behind the old gas station with the flickering light. The air was cold enough to sting, but the restaurant’s neon glow pulsed like a heartbeat in the fog.
The drive-thru speaker crackled, and a calm voice said, “Welcome to Jack in the Box. My name’s Tyler. You can take your time.”
There was something comforting about how he said it — slow, deliberate, like he’d been waiting just for me.
I ordered a Sourdough Jack, curly fries, and a Coke. Nothing fancy. But as I pulled up to the first window, I noticed something strange — the glass reflected the parking lot behind me perfectly, except… there were no cars. No me. No movement. Just the still neon bleeding into gray nothing.
Tyler wasn’t at the window at first. I could see the kitchen lights flicker through the narrow slit between fryer and counter. Then, softly, the window slid open.
He smiled.
He had that generic, tired fast-food smile — but his eyes were bright. Too bright. Like he hadn’t blinked in a long time. His name tag read TYLER ☺ — the smiley face was printed, not drawn.
“Sorry for the wait,” he said. But I hadn’t waited. The order was already in his hands. The fries were steaming, the burger perfectly wrapped, the Coke sweating cold in its cup.
I don’t remember paying.
I thanked him and drove off, but when I reached the light, I realized I could still see the restaurant in the mirror — even after turning the corner. It shouldn’t have been visible. The sign kept glowing through the fog, the letters bending, stretching into something else.
JACK IS BACK
No. It said TYLER IS BACK.
When I got home, I opened the bag.
The fries were still hot.
The burger still fresh.
But the receipt — the receipt just said one thing, printed in faint red ink:
> “COME BACK WHEN YOU’RE READY.”
“WE NEVER CLOSE.”
Thanks, Tyler. The food was great.
I’ll be seeing you soon.

Have placed a few mobile orders + a few drive-thru orders over the years. Food is always hot and ready quickly. Staff is friendly and on top of everything and have always had all of the condiments, never missing any of the order.

I got a #14 with extra lettuce which was extra … the sandwich it was built like a mcChicken .. I only got 2 BLACK NASTY SOGGY lettuce leaves . I was a fan of Jack but after this . Not worth paying so much money on it if im receiving a flat sandwich with soggy lettuce. The iceberg lettuce was so much better than this .

This is a 24-hour fast food restaurant, the traffic location is very good, many cars will line up here in the middle of the night. I like the French fries here best. I often buy midnight snacks here, I like it here

I’m going straight to the food on this survey. Tacos are so good. But I need a strawberry shake to cool my mouth. You see I’m a weakling when it comes to spicy food! And they really are not that hot… LOL. I really enjoy taking a Jack in the box survey to get free food. They give you a good option between breakfast croissant and a jumbo Jack with cheese. Buy one get one free! We all love free right?????

One of the cleanest Jack in the boxes I’ve ever encountered in Los Angeles. Friendly staff. Food on point. Did I mention how clean the bathroom is?

Why do I have to wait in the Drive-thru to pick up the delivery order after 10pm? It’s really unreasonable. It wastes me 30 minutes or more every time! ! You only open the door once for the driver. Are you really that lazy?

We were at the window and did not get a response back when we said, “hello” once Kayle answered she kept cutting off my sister in law and saying, lie that it? Is that it?” My sister in law stopped talking because she kept cutting her off. Once she stopped my sister in law then continued to order and when Kayle was asked a question about the combo she would say, “yup” instead of answering the questions. We pulled up and she continued to have attitude. Once we spoke to the manager she also had attitude. We got the recipe cut off. The information for the Jack in the Box was cut off. This was the worst service we’ve gotten here and we live right down the street so we are always there and have never ever ever gotten this bad of service.
