I would check with the Goodman Theater to get the time of the final curtain. Since Petterino's is attached to the restaurant you can make a reservation for right after the final curtain.
You can get show running time from Goodman. Blind Date runs 2 and a half hours.
We did a 3pm matinee at The Oriental and made a 5:30pm dinner reservation. We were just fine. I would check with The Goodman on the running time of your show.
