I went in the summer to see the Terracotta Warriors. I was a little disappointed as the price was high and the exhibit was small. What they did have was well laid out though. I like to have an audio-guide and that wasn't an option here...you had to download it to your ipod before you came. Compared to King Tut at the AGO I thought this not as good. The gift shop was spectacular though...I bought a really neat Chinese Calligraphy kit for a teen for her birthday.
The dinosaurs and the bat cave are really cool. Too bad it is too expensive for a lot of families.....
