We went to Taipei from 19-24 Dec, with a few families from the kids' school. This is actually my first time to Taiwan, although I have attempted twice before.
For this trip, we did not go out far from Taipei city. We stayed in the Grant Hyatt. Before we went, I checked the hotel web site, and they say the hotel is in the same complex as the Taipei 101. It's true that the hotel is only 5 min walk from Taipei 101, the hotel building itself is quite old with low ceiling. Whilst Taipei 101 is very new.
With so many kids around, we chartered a small bus to take us around.
The food in Taipei is generally very good. From upscale restaurants like 高記小籠包 & 欣葉台灣菜 to street food in the various night markets. Even simple soy milk breakfast in small shops were good.
I got many chances to take taxis in Taipei - when I did not feel like going to kiddie places or after the other families left after 3 days, we took taxis everywhere. And it's very impressive that we almost all have good & friendly taxi drivers. Most of the drivers were almost too keen to help and recommend places to go, or things to do, or bits and pieces of information about Taipei. This contrast very sharply to the taxi drivers I encountered in the mainland China (and the very few times that I used taxis in the US.)
I almost never shop for 手信 when traveling. But after I came back to HK, one of my regrets was not buying some 太陽餅 & 鳳梨蘇 freshly baked from some of the shops we saw. The almost only purchase was some whiskies from the airport duty free.
