At the back of this building there is a drop where you can take a glass elevator to the ground. It was quite different, I've never seen an elevator like this in the middle of a city - and it was free! It was actually kind of scary because 3 walls were made of glass. I met someone sitting on the bench next to me and she took the elevator with me.
When you get off you're in a little inlet of shops and restaurants. Even though temps are cool everyone still prefers to eat their meals outside (almost all restaurants I've seen have heaters however).
