The Pearl Building in Shanghai is a really cool site. It is manly used as a TV/Radio station and tower. That occupies the 1st main pearl. They have a see through floor, a post office and a revolving restaurant in the second pearl. Where the tourists go. The see through floor was really cool. It was like you were walking on air. We were very hungry and decided to stay high up in the sky and eat at the revolving Chinese buffet. It was fun and the view was nice even with the smog/pollution. The food was better. Lots of things to choose from (a.k.a. buffet). At one point I missed an entire section of the buffet. However, you know me, when I found it I tasted each and every plate. It was a fun experience.
