I think what I love about the Gershwin is the lobby and the path to the house. It just feels like you're on the way to an adventure... if that makes sense.
Interior goes to the Hirschfeld. I love the sloping shape of the boxes.
Overall, Shea's Performing Arts Center in Buffalo. It's been mentioned MANY times on this board in previous threads. I love going home to walk in it. The lobby is beautiful, the hallways to the mezz, the colors inside the house... love it all.
