St. Patrick River Dye Weekend -Where to go for slightly older crowd?

We are looking to travel to Chicago for St. Patricks Day dyeing river weekend, March 13-16 It will be my mom (65yo) and myself (30yo).  We drink, but I don’t want o take her on a bar crawl or at a crazy party bar.  We know it’s going to be crowded and that’s fine.  Do you have any suggestions where to go to eat or things to do on the day of the river dying?  Or any of the other days that weekend?  We have a hotel room on the Riverwalk facing the river so we can watch it from there.
