On clear days, it's hard to beat the view from the Nanpu river in the South of Shanghai.
Tickets cost 68RMB to go up the elevator to the start of the bridge's arch. From there it's some 360 steps to the observatory deck at the top.
From this point you can see the Expo site (opens in June 2010), and the city laid out like a map as far as the eye can see: The Pearl Tower, the Financial Centre, People's Square, and miles of skyscrapers in every direction.
Ticket office at the very end of Lujiabang Lu (near Xietu Lu).

Updates
totally agree, but its the Lupu bridge not the Nanpu. Great view of the expo site now as it is almost finished. Tickets available at the end of luban lu, under the bridge.
Is this your business?
