Use Spot Hero app. Does all the work for you!
I parked in self parking garage 200 w Randolph which is about one block from the theatre to the right as you cross Wells. $15.
Parking on Franklin & Randolph is pretty reasonable. Its a short walk from the theater.
No Parking facility connected however parking facilities on the next block of the theater or valet with hotel next door
