 The Bar scenes were shot in a S&M club in Manhattan which is now  know as "The Hellfire Club". The bar was so big that they also used  it as the Bradleys basement and the crew had to hide all the sex  toys including a large swing (which is still in the club to this  day). The original buzz saw used to kill Duane and Belials father  used to hang above the door of the club until it was eventually  stolen.
