I was in here last weekend. I was sitting eating away merrily when I couldn't help but notice the very string smell of fish. On looking round I was then surprised to see that this was indeed fish. It was the period between lunch and dinner and the staff were on a break. They were sat at the table next to me eating a fish. I don't mean some HK mock fish or taro in pastry shaped like a fish. It was a fish. At the end there was a skeleton of its bones around which they had carefully cut away the fish meat.
I question whether that means that is a genuinely 100% vegetarian restaurant. The customer menu may be all vegetarian. The kitchen certainly doesn't appear to be all vegetarian.

As the other reviewers say there's also a take away place facing the street.
It's like a bunch of other all vego Chinese places in HK. Worth eating from if you are in the area but there's no special reason to make a trip to here if there's a similar place already closer to you.
Cons: Staff cook and eat fish on site
