The Knick is back!

The Knick is back with this stunning dance hall.  I believe the show is shot in New York, so where is this place?  If it exists, I am going.  

And feast your eyes on Room-Of-A-Thousand-Drawers:

And Room-Of-All-Cabinets:

UPDATE: After completing the season, I am lead to believe that the dance hall was probably built as a set on a sound stage....but I would love to be wrong.
