This is one of the only 24/7 resturaunts in Boulder, I and many others tend to visit it often. The service is great. The food, compared to other Jack in the Boxes is great. For a fast food restaurant, this venue is definitely 5 stars. The coke freestyle machine is great as well.
I haven't been on the inside for a while, so I am not sure how clean the seating area is; however, there is a lot of room and restrooms inside.
