This is a pretty good airport.
I have a flight from Los Angeles to Macau last week with a stop in Taipei airport to change plane. This is a pretty good airport. It is clean and tidy. Drinking fountains are easy to find. There is a little restaurant selling super delicious japanese noodle in bone soup with tender pork and vegetable, Danish milk pastry is awesome also. It takes a while to line up but it is worth the wait. There is also a mini version of the national museum exhibiting several antique pieces. The museum store is just right by the side and offer a wide range of Chinese Museum items. Very nice! There are couple of shops selling the famous Taiwan beef jerky, ethnic Taiwanese sweet treats, perfume, wine, cigarettes and brand name handbags. I also find a small recharging station outside one of the shop. It is for all kinds of cellular phones. If you are a customer of the shop, you are entitled to use this service. All the shops and restaurants accept Hong Kong Dollars, US Dollars and Taiwanese money. Pretty cool!
On the second floor, there are airline lounges for business and first class customers.
