I am taking my wife to NY from London for her 40th birthday in April as a surprise. We arrive Friday evening and leave Sunday night. We would like to spend some time taking in the 'buzz' of the city that never sleeps. I also want to be able to get a good view of the famous skyline, and visit the 9/11 memorial. We are staying in thele Parker Meridien on West 56th Street. Also, any redcommendations for a late night romantic drink in that area would be very much appreciated.
