Have to say I love all of the theaters in Pittsburgh, but the O'Reilly is really quite perfect. Not a bad seat in the house at all. The variety of shows they bring in are awesome. Most recently saw The Diary of Anne Frank. Really top notch performance. I've seen comedic shows as well and this theater fits the bill for all.
My favorite part of this place is the intimacy of the seating. If you have stage side seating you really feel engrossed in the show and part of the cast. And, to boot....the seats are pretty comfortable!
Reasonably priced and located smack dab in the center of food heaven up and down the street. Definitely look for a show to see here.
