Northern Illinois University/Dekalb, IL ?

I'm going to be in Dekalb next week for work....I'm only going to be in town for a day. I need recommendations of something close to campus...I'll be at the Convocation Center...probably get lunch break around 4:30/5:00 and I'll only have an hour...so the closer the better. Looking for pubs, diners, pizzerias, anything quick, but no ethnic foods.

Also, any late night places for something to eat after a basketball game? Again, pubs, pizza by the slice places, etc. Has to be in DeKalb...won't have time to really go any place else....the late night place can be anywhere in town...my hotel is near I-88, but I'll go exploring if there's someplace interesting.
