We visited late on a Saturday afternoon, as the sun was beginning to go down and we saw some excellent views. It wasn’t too busy. It’s a big, tall building that allows you a 360 degree view of inner city Shanghai, so you should enjoy the views, provided there’s no cloud cover. The lift journey up was quick, but they missed a trick by not having the lifts on the outside of the building with glass walls. You’re in a four sided metal box and you can’t see anything to get any perception of speed. There isn’t that much else to see in Shanghai, so it’s well worth a visit.
