Im a vegetarian, so fast food can be challenging. I recently found out that they sell grilled cheese sandwiches. They are pretty good. The price is good as well. You can customize it to suit your taste. I like to add tomatoes. Its a good late night snack.

Horrible. I stopped by here after work because I wanted a burger. I ordered a classic smashed jack and I said it clearly. I should have checked the bag, but who could screw this up. I got something completely different, looked like a tortilla something. I showed it in the picture. I did not want this garbage. I want my money back. This is wrong on so many levels, I will never buy food from here again. You guys ripped me off and gave me garbage. Im not going to eat this , this is horrible. It doesn’t even resemble or sound like “classic smashed jack “, what were they thinking? Can I have my money back please, I’m not going to eat this.

Went to see a concert. It is fairly hard to access this venue. When you get there you park and have to hike very far to get to the event. It’s all uphill in the foothills. The food is ridiculously priced. $25 for a hamburger. $10 for a soda. They do not take cash for anything so you have to purchase a special event mastercard. Getting out after concert is a nightmare because only two small roads lead into the event space.

Rude service.
The lady had an attitude and argued with us after getting our order wrong.
Then, instead of making a brand new milkshake, this lady just dumped the old one and re-used the cup to give us the new one!

I usually don’t leave reviews, but I’ve had enough with the service at this Jack in the Box location. The staff are constantly distracted and not paying attention to their work. During my most recent visit, the employee almost forgot to give me my change and instead started handing me another customer’s order. This kind of disorganized service has become a pattern here—workers seem more focused on chatting or multitasking than actually taking care of customers properly. It’s frustrating and unprofessional. I hope management takes notice and makes some much-needed improvements.
