Years ago, I attended a performance art/theater project in NYC where you visited different locations around midtown and saw installations, small scenarios, etc., very cool but hard to describe. ANYHOO, at one point our guidebook directed us to enter an Applebee’s in Times Square, walk through the restaurant and out the back door.
Upon opening the door you were greeted by the remanants of the grand lobby of an old 19th c. theater.
I googled it and here it is.
It was amazing.
