I have most of the times every month a nightstop in NY. I always visit the internetpage
www.nycvisit.com in advance where you can find very nice locations and things to do. A suggestion from my side: Just go once not to the typical places but go to Greenwich Village. Very nice area, good restaurants and bars and most of the times not overfilled with tourists.
Also nice to visit the site of the Radio City Music Hall for maybe a nice concert at this time.If you wanna get reduced broadwaytickets in advance to buy via internet you have to go to
www.theatermania.com
Have fun and let me know how it was.
