I 1st went as part of the local meat free meetup group in Sep 14. As has been said already its a pay by weight buffet. Current price is 19 hkd per 100 grams. There must be a lot of water absorbed into the food as mine wasn't especially big but was 80 odd bucks. Its then serve yourself on unlimited soup, congee, rice and soupy red bean dessert. The food I had was nice enough. The 8 choices to serve yourself for the main were all vegan tonight.
As an alternative to the pay by weight buffet they offer 3 noodle dishes at around 50 dollars each. This is still accompanied by help yourself to unlimited soup, congee, etc.
One thing that could've been better is that the seating / tabling is a little on the cramped side. They of course though can only operate within the space that they have.
Cons: Slightly cramped seating
