A decent fast food joint in Missouri.
Haven’t had Jack in the Box in well over a decade so decided to stop while driving across the state of Missouri.
Overall it was alright. They have a lot of variety, breakfast all day, burgers, chicken, Mexican, even wings.
First of all the service was good. Our cashier was very nice and helpful with the menu.
I had the tacos which I’m told they are known for. I have no idea why. They were not good. Not awful or anything but just sort of disappointing. I also had a small cheeseburger, it was OK. Nothing special but decent for the price.
Everything was cheap which was nice, so I would say I got about the value I paid for, so it’s nice to see actually inexpensive fast food.
My cohort had the Chicken wrap and curly fries. He said the wrap was so-so. The curly fries were good though, the highlight of the meal.
Overall it was OK. Nothing special. I would put it on par with the big 4 fast foods, you know the ones.

I paid $16.00 +tax for 2 orders of chicken teriyaki bowls. I get home after an hour and half drive to find just 2 bowls of rice. That’s right white rice only. I have been calling the restaurant ever since I got home and no one will answer. I tried calling other corporate numbers etc… they are fake numbers. All I want is to be reimbursed. Jack n the box is much more richer than I am. I am on a fixed income and my husband has been out of work for over a year with cancer. So eating out is a treat for us.we went to visit family for the first time in over a year and on the way home we stopped at jack n the box because there isn’t one where we live. Shifty customer service for sure. You must have a lot of complaints so therefore you don’t answer. Now wonder so many jack n the box restaurants are closing .

I ordered a cheese burger with meat and cheese only for my grandson and a teriyaki bowl for myself. The burger had everything on it and the bowl had the rice already was brown from sauce I guess. It is always white rice on the bottom, but everything was already mixed together. So not going to eat that. It is like someone gave me their bowl they already started. I tried calling through Sunday and no answer. I paid $20 dollars for food I didn’t eat. So sad!! I have always loved JIB!

So I was wondering, why Jack in the box is complete trash every single location I go to? There’s still 30 minutes before this place closes and I just wasted 15 minutes out front putting in an online order through the app only to find out at the end of the order that I could not place it “because this location is closed” . This location is not closed. The quality of food, the quality of service, and the quality of your technology is complete garbage, so thanks again for nothing. I completely regret trying to order Jack in the box again after 3 years of not ordering Jack in the box because of the same BS. I guess I’ll see you again in another six.

Don’t come here if you want your food in a timely manner.
Stopped by driving home at 6:05 and ordered four tacos and a pack of jalapeno poppers. Sat behind one other car for 5 minutes, paid, then got asked to pull around. Both me and this guy waited another 15 before our food was handed to us. Twenty minutes for two bags of fast food between the both of us is astounding. To kick, I wasn’t even asked if I wanted any sauce. I couldn’t even go inside to ask for any since the lobby was locked. Now I’m stuck eating my food dry. Y’all gotta do a lot better.

We did an online order for breakfast and when we got there, there were only 2 cars in front of us in the drive through. We pull up to the speaker and before we can say anything we are told “sorry we can’t take any orders right now.” No we are waiting to get out of the drive through line. We obviously want a refund on the food we ordered but don’t see how to do that on the app. This place needs to be shut down if it can’t even provide service. Put something more reliable here.

I usually stop in here every time I head toward St. Louis. I haven’t had an issue here in a long time. My last visit however was around 9:00pm. The crew obviously didn’t have a manger on duty because they weren’t making food for no one. I was in the drive through for about 20 minutes and the two cars in front of me never moved. I decided to go inside. Went I went in and saw no one at the counter or window I didn’t know what to thing. There were people in the back but it was obvious they weren’t worried about doing their jobs. I was there for about 30 minutes total and never placed an order.

I’m writing to report an issue I experienced at your Warrenton, Missouri location on October 11, 2025, around 7:30 PM. When I arrived to place an order, I was told the store was “closed due to low employees.” However, I could clearly see at least three employees inside the building who refused to provide service and had already closed early.
This was frustrating and disappointing, as the location appeared to have enough staff present to serve customers or at least communicate more clearly about the closure. If a store must close early, there should be proper signage, updated hours online, or another form of notice to prevent wasted trips.
I hope this situation is reviewed and addressed to ensure more consistent service and accurate communication with customers.
Thank you for your time and attention to this matter.

Gina is my soulmate! She handled every problem with poise as she took my order. After two horrible previous fast food experiences, without naming names (they had Golden Arches), you want something your way? See my girl Gina in the drive through window at Jack in the box warrenton. -Connor

Quite possible the worst Jack in the Box ever in history. They haven’t been able to find reliable or presentable employees in over nine yrs of living here. Never have the shake machine running and you be lucky to see all the ingredients on your tacos… don’t ask if you need condiments or napkins in the bag, this place real sucks every time I’ve been to this location
