Additionally, the excellent public transportation meant that spending time walking outdoors (to the subway, etc) was much more likely than in a city where you are just walking from your office to your car. Just my 2¢.
Other than that, I agree. Well, and also the giant, flying cockroaches. They're pretty bad too.
Or Tainan. Tainan was awesome too.
The road signage and markings are identical to my home country of Canada. People drive on the right. The electrical plugs are the same. Almost all of the road signs and public transportation signs are in English as well as Mandarin.
The one notable exception are the Taipei city buses. Those are Mandarin-only. I guess they don't expect too many foreigners to be taking those!
