It depends on where you're staying. I suppose you're not likely staying downtown (that will cost you an arm and leg) but staying somewhere on the north side...
We usually stay all the way out in Willowbrook at 55 and Kingery, but we don't have a problem going to other parts of town. We like to experience all that Chicago has to offer.
Lou Malnati's is awesome, has anyone been to Connie's Pizza on Archer we usually end up going there, the pizza is great and so is the bread.
