One of the most famous clay pot rice restaurants in Hong Kong, there's always a long line especially winter. It is popular not only among locals but also tourists.
I recommend also the deep fried oysters 蠔餅 for oysters fans. It is an evil dish but the crispness is satisfying. For the clay pot rice, I don't need to say much it is just above average. Make sure the rice stays longer and don't mix the bottom so you can eat quality crispy rice afterwards. No reservations so get here as early as possible would be a better chance to wait less.
