I was just looking through the theater options for Pinkfest 2016.
My first suggestion is a musical comedy called The Bardy Bunch. See the website with a description of the play at http://www.thebardybunch.com/pages/about_us.html
It may be hard to find something as good as last year's play, which I really enjoyed and at which I found myself coveting a certain pair of shoes.
Another option is Smokey Joe's Cafe out in Oakbrook. Information at http://drurylanetheatre.com/shows/16-17
It's a little ways out. At first I thought it was in Oak Park, but I was confused. I'm leaving it her as a possibility anyway.
The Theo Ubique is doing FLY BY NIGHT. Brief description here. This is where we saw Blood Brothers last year (mentioned above).
These are just suggestions, please make others.
