I can't agree with you on that point. Over the course of the past 20 years, I haven't had reason to go to that location more than 10 times. People's Square (nearby) is on my circuit occasionally (e.g. every 6 weeks or so), and is a major transport hub, but I wouldn't describe it as most "central" either simply because there's not much between there and the bund. 2-3 km west of there is "central" in my book.
