I am attending a concert in the Chicago loop next week. I would like to grab a bite close by before the?

concert. I'll be dressed casually, and, since I'm going there primarily for the concert, I don't want to spend a lot. Does anyone know of a good, fairly inexpensive restaurant in the loop? I would prefer a seafood restaurant, or one that at least has seafood on the menu.I am attending a concert in the Chicago loop next week. I would like to grab a bite close by before the?
Try McCormick and Schmick's at 1 E. Wacker Drive. They have a pretty decent seafood menu with entree prices starting at about $11. They also have daily meal and drink specials. Or you could just order a couple of appetizers.
