I was going to suggest Lou Mitchell's
565 W Jackson Blvd, Chicago, IL 60661 · 312-939-3111
There is typically a line on any Saturday morning...but usually not much more than a 15-30 minute wait. But as a plus you get to munch on some donuts while you wait.
In fact last time I was there (last winter) the Illini were playing at the UC and the place was FULL of Illini fans and their orange garb...so might be a good place to get in the spirit before the game.
Another place that is very close to the UC and most times very good is: Wishbone
1001 W Washington St, Chicago, IL 60607 · 312-850-2663
