According to Wikepedia "The theme of the exposition will be "Better City – Better Life" and signifies Shanghai's new status in the 21st century as a major economic and cultural center. It is expected to generate the largest number of visitors in the history of the world's fairs in terms of gross numbers."
Starting in May of 2010, when Shanghai welcomes everyone to The Worlds Fair, this city is going to be the place to be. Actually, right now, its the place to be. And to get a REALLY good view of the high tech skyline...THIS is the place to be. At the top of the Hyatt on the Bund, where cool music, great wine, tragically hip people, and good times meet. I know where I wanna go back to!
