>Are there any other "lost" Broadway theatres that are still functioning that you can go into? I remember hearing about one that was turned into a banquet hall or something that was connected with a big NY hotel. Anyone remember that name?<
Apart from the Eltinge/Empire, which serves as the entrance for the AMC 25 complex, and of course, the Hellinger, there are four other former theatres in the Broadway theatre district that are being used or earmarked for other purposes.
The first theatre you are referring to is the Liberty, on 42nd Street, which is now Famous Dave's BBQ. If you enter the restaurant, the theatre is intact, toward the back. You can walk in and take a look around. They restored most of the remaining interior details and apart from some oversized light fixtures they've added, it's quite attractive.
The Times Square is also on 42nd Street and is the theatre that is supposed to become some sort of interactive 4D Broadway musical experience.
The Hudson, the second theatre you mentioned, is on West 44th Street, down the street from the Belasco, and is part of the Millennium Hotel, and is used for corporate events, catering, etc.
The Hammerstein is on Broadway at 53rd Street and is the Ed Sullivan Theatre, home of The Late Show. Its original interior was quite spectacular.
Begin at the beginning and go on till you come to the end: then stop.
