The food that I tried there was ok, some quite nice, some rather bland. My main challenge was the communication. I do speak some basic Mandarin, but they seem simply not oriented towards non-Chinese speakers. If you can explain that you only eat vegan, no meat, no fish, no egg, no dairy, be prepared for lengthy explanations in Chinese (of which you will not understand much) and possibly leave with an empty stomach.
The English menu does not help much more than in identifying the dishes that obviously do have meat in them (many), but the 3-word-descriptions of the dishes does not say much about the suitability for vegans.
* Update * They do not seem to have the English menu anymore, so now - unless you can read Chinese signs - the only option that you have is to compare the pictures on the menu with the pictures posted here on Happycow. So, it has become even more of a challenge to get vegan food there.
Easy to find, and possibly a good choice if you speak decent Mandarin

Cons: Communication in English near impossible, prices not exactly cheap
