Please, I know it’s the end of the day but please please I was really looking forward to my curly fries all day. If I pay for my curly fries serve the same as you would early on the day…its like I got the scraping from way at the bottom. Just make a new badge please

Jack is also a favorite. I’ve tried everything they serve and the only thing I rarely buy is their tacos and not because they are not good but because I’m Mexican and if I crave tacos I will get thr real thing “Tacos de Cabeza or Lengua”. I go for their Hamburgers and Sandwiches . It’s all tasty and delicious.

I like this jack in the box because it’s always open on the holidays and my job makes me work on the holidays, so I eat here on thanksgiving. The wait here is rarely long, even during lunch hours. The food is always decent, everything that you would expect from a jack in the box. The prices here are always cheap too, unlike the others.

I rated this place once a month or so ago but I’m taking the time to rate again – I want to make it at least 3/5 stars, but i dont feel this place [on this visit 5-27-25 at 13:00 hours] earned it, sadly..
The crew working hardly acknowledged me or other customers present, didn’t greet anyone, didn’t smile and actually at one point they seemed confused on the orders… there were 2 people in the drive through & 5-6 people inside…
The bathroom was not cleaned, yikes…
But Good Things – the food was good. It was made quickly: 2-3 minutes and it was accurate.
But i cant say i want to return or recommend this place. I hope management makes adjustments in the future.
