I didn't know what to expect, but I was just told to go there, so I did. Really happy I did. There are a number of different aspects to this, but for me the model of the city was just amazing! Its not all of Shanghai, but its a lot of it. They literally attempt to model building by building in some areas. Really impressive (and there's a day/night sequence worth catching every 10 minutes or so).
See the past, see the future, in a very unique way!
