I'm not usually one to be amazed by a bar but the Hyatt on the Bund's Vue is worth all the praise. It is 32 floors up overlooking the Huangpo River. From one angle you see Shanghai's most famous western architecture, The Bund (the second picture below). From the other angle you look into Pudong with its mega skyscrapers.
I am consistently amazed at the ability of Shanghai architects to light their buildings. Some seem to look better at night than in the day. In the image below you can see the Pearl TV tower in the foreground with the Shanghai Financial Center just behind it. Many of the buildings have mini light shows/videos projected on their sides every night. The glitz can seem saccharine but I have gotten sucked in like a little kid at the county fair.
The kicker of the night was the marble hot tub that was the cornerstone of the outdoor terrace. It was surrounded by small tea rooms with a large gazebo covering the entire terrace. If you didn't remember to bring your suit you could purchase one for about 200 RMB ($30). Most people just sat with their legs in. It was such an unexpected part of this elegant skyline environment.
