Are they as good as the Taiwanese? I heard KL has pretty good ones but I wasn't sure if this is the one?

This is just ok to me, as I've known better authentic Taiwanese desserts. This shop is listed that's why I try. The other one you can try (and taste better) will be Xu Liu Xiang

S'pore used to hv Xu Liu Xiang but closed many years back. M'sia outlet still ard? I dun seems to find the outlet in hk the last I visit, the one at the harborfront is no longer ard:( I still cannot find one that matches JiuFen taro.

Yea. Jiu Fen taro is the best.
