^^Hello sis, travel time from the airport to Taipei city takes around an hour (one-way). Terminal 1 is under renovation so most shops are still closed. But Terminal 2 has some shops... I don't remember masyado since I've only been there once...
Food - try to check this site for recommendations:http://hungryintaipei.blogspot.com/
I'm not much of a foodie but even I have heard of this famous blogger when it comes to Taiwanese food/eats.
One of the most famous restos here is Din Tai Fung but you have to wait to be seated sometimes (like 30mins to 1.5 hours).
^Good choice, sis!
The weather is mostly the same as HK... cold and damp.
Taiwan is relatively crime free, like Singapore. No worries there... But unlike Singapore, English isn't widely spoken here. Medyo challenging if you can't speak/read Chinese. You'll see English signs but you can't read them aloud and expect people to understand you... Mandarin is a tonal language kasi. Hmmm, as long as you have a solid itinerary, you'll have fun
