I have been eating at The Chuck Box for years and despite all the influx of high end burger joints, this is still my favorite burger in town. In fact, I am giving a five star rating here purely on the hamburger, which is absolutely delicious.
Another positive is the condiment bar for the burgers. It is well stocked, so you can add what you want. The fries are good, and I like that they don't offer a huge portion at an inflated price like some burger joints in town.
As another reviewer alluded to, this restaurant definitely has character. It can get very crowded and parking can get sparse, so try to go during off hours or when ASU is not in session. it is also cash only, though they do have an ATM there.
