I went as part of the local meat free meetup group. As has been said already its serve yourself and pay by weight. 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.
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
