The 101 Building in Taipei, Taiwan.
I went there earlier this year during my four day trip to Taiwan.
It's a pretty impressive building, with a lot of upscale shops, and pretty decoration ("glass, we need more glass. Glass is the key to natural lighting and high electricity bills")
Truth be told though, the only thing I was really interested in while I was there was the huge PageOne store that was located on the top floor. (Books, people, books!)
