This is one of my favorite Hyatt properties. It is extremely new and is pretty spectacular. The hotel is situated on the upper floors of the Jin Mao Tower in Pudong and reaches up to 88 stories. The F&B is excellent, with great Chinese and Western restaurants. The attached club (part of the Hyatt) is always fairly packed as well. When I was last there (February, 2001), it was considered to be an extremely trendy spot.
The only thing I don't like about this property is the size of the rooms, which run fairly small.
It's hard to imagine that you would be disappointed at this property.
