I used to come here all the time when I lived at the dorms. Don't come here much anymore, but I do try to make it down once or twice a year.
Chuck Box is some of the best burgers and chicken sandwiches in town. You see your whole meal made right in front of you, which is great, plus they have pitcher beer (nothing special, just standard American piss beer). The chefs are very animated and will be more than happy to help you make your choice (as long as there isn't a huge line). Once you have your burgers and fries, you go to the topping station and customize your meal. This is my favorite part. Can't beat their burgers with onions, pickles, ketchup, lettuce, the works.
It's pretty irritating that these guys don't accept credit cards--I always forget this before I come and I end up needing to scramble to the ATM. BRING CASH! There is a Bank of America ATM on 7th caddy corner from this place and I think they have some no-name bank ATM inside. Also, parking is tricky so just be sure you don't get towed wherever you decide to park.
