Taipei 101 is Taiwan's highest building and was actually the World's tallest building until 2010 (before Burj Khalifa in Dubai). It is a couple of minutes walk from the train station. The building is so tall, you'll need to find a spot few blocks away if you want to snap a whole picture of it.
On our quest to find the best spot, we passed by some cool decorative balls which were great for wide angle mirror pics. 😉
