This is a pretty big restaurant. It reminds a bit of the likes of Three Virtues, Gaia, or Paramita for anyone who has been to the likes of those. It is located diagonally opposite on the same junction as another all vego place in case you want to take a look in the menu at that place to widen your choice a little.
I was with a native Cantonese speaker who asked if a dish (baked mixed vegetable satay) contained milk. We were told that it did but that the milk was an add in during the cooking process and could easily be left out. Sounded good so that's what we ordered. When the dish arrive it appeared to have a coating of cheese or a cheese sauce. On enquiring with the waitress, sure enough it contained cheese. No issues in having a fresh portion brought to us without the cheese.
Both main dishes ordered were tasty. My co-eater also ordered a soup. 202 hk bucks for the lot.
I would happily eat here again if I were in the area. There's a ton of places like this dotted over Hong Kong. I personally wouldn't make any sort of a special journey to eat in this place.
