I love the Benedum. Really there's not a bad theater in Pittsburgh, but this just has my heart. Recently just saw the Nutcracker, but have seen many a show here.
Plenty of parking garages in the vicinity so not a far walk once parked downtown. Great restaurants nearby.
Pricing is good, too. I love that they offer discounts to teachers. Yay! They also do student rush tickets, too I believe.
Trust Arts gets a great selection of shows to come to Pittsburgh so you can see a great Broadway series production in your hometown or if you visit Pittsburgh. And, in that case this is something to do on your visit.
I sat most recently in the orchestra seat which are nice. I prefer the director's circle above so you don't have to dodge a head in front of you. I did once sit in 4th row orchestra and well, that's pretty damn awesome!
I will always be back to this theater.
