Given my (and my friends') preference to eat vegetarian food, the name of this place says all there is to know about that. Servers always ask if egg is OK (even when ordering an egg dish) and no alcohol is served. I've also not seen onions used (to the best of my recollection) there for people who have that restriction as well.
The food is consistent and tasty, but far from "gourmet". The veggie meats are the best I've tried most anywhere, admittedly that isn't a great list as I stopped trying other places after this one. The menu is MASSIVE, including all sorts of dishes for those accustomed to Cantonese (and some more northern-inspired) cuisine as well as the uninitiated palate.
