Who knew that Cleveland was known for the arts. I came to see Wicked earlier in December and thus my first visit to PSC. I've seen shows in Chicago and NYC and their theaters tend to be bigger, but PSC definitely is appealing and a place not to be missed, even if it's to come and admire.
Paid parking is across the street, but if you're up for a little walk, sometimes you can get free parking. The theater lobby is amazing and most seats are good views once you get into the theater. They have food/alcohol/beverages available but like any production, expect them to be on the pricey side.
If you have a chance, come and visit, see a show!
