I've been backstage at Studio 54, the Vivian Beaumont, the Walter Kerr, and the Laura Pels (Off-Broadway), and they have all been extremely different.
I wouldn't say once you've seen one, you've seen them all.
Studio 54 is like being in a cramped old attic, while the backstage space at the Beaumont is all brand new, renovated, spacious, and gorgeous. The dressing rooms look like fancy hotel suites. The Kerr is multi-leveled with a few dressing rooms on each floor, and with the exception of two star dressing rooms, only one bathroom per floor.

"I have also met him in person, and I find him to be quite funny actually. Arrogant and often misinformed, but still funny."
