I think Shanghai gets my vote as most modern looking city, in what I've learned is a contintent of otherwordly architecture by viewing the top 15 skylines in the world. http://www.diserio.com/top15-skylines.html
Hong Kong appears a close second, along with Kuala Lumpur. But New York still ranks in there as one of my favorites. I've got some travelling to do, and associated money to make.
