Blatt Billiards on 38th between 8th and 9th in Manhattan.
x2. I don't think there's another building on earth that has a larger variety of Pool tables (manufacturer, models, and age) than Blatt.
They alos have a heck of a lot of cues for sale as well. They are the proverbial Candy Shoppe for big kids who shoot Pool.
Blatt Billiards is no longer in that building. They have a new location. Mark Finkelstein will have the address.
