When I visited Taiwan during the Summer of 2004, I was quite disappointed to see what looked like the completed structure only to find out when I got there that it was still under construction and not ready for visitors. The other day, Taipei was presented with a clear day so we decided to catch some views from 101.
The tickets to the 89th floor indoor observatory were relatively inexpensive at $320 NT per person with my aging Eastern Michigan student I.D. card.
The building hosts the fastest elevators in the world which carry passengers to the 89th floor in 37 seconds at 1010 meters per minute.
