quick access, it was the fastest elevator ride i have had! too bad weather was a bit gloomy but the view was still spectacular.
've read many reviews saying this was not worth the amount of money (ie. it is very expensive, but only in comparison to other things in Taiwan) but I for sure felt it was worthwhile. Visited on a Sunday lunchtime hoping to buy a ticket in advance for the following day, but arrived to find it almost empty and with an "excellent" viability rating I would have been silly to not go there and then. Great views of the city and interesting to learn about the damper (the thing that steadies the tower during earthquakes and typhoons). Outdoor observation deck not the best but the windows indoors are great.
Avoided the long queu with this Klook booking. Had a lot of information learned about the Taipei 101 building. One of the most-visited tourist attraction in Taipei.
Taipei 101 is always a fun place to visit, no matter how many times I've gone to it. I just wish I picked a day with better weather!
