My favorite Lantau Restaurant is the China Beach Club located in Mui Wo Lantau Island.  15 Minute walk along Tung Wan Tau road from teh Mui Wo ferry pier. Western / European Food - Awesome ! 

It sounds confussing but its easy to get to on the main road of 18 Tung Wan Tau Road. Basically right along beach and on the second floor with a balcony and view of the beach.

Its really nice and give you a feeling of home.  You get very large portions and Definetly try the Greek Salad and Garlic Home Fries !   Much of their food is Barbecue fish or meat !   Delicious.
