Well, as an example, if I had the price of a Michelin 3* restaurant dinner for two to burn, I'd rather take a
private boat trip out to
Ming Kee on Po Toi Island and have very fresh seafood lunch or dinner there. Very basic environment, but the chilli pepper squid is superb, as are the steamed prawns with garlic & spring onion. But it's basic. Bring your own wine for a very reasonable corkage (like $HK50 per bottle if I remember correctly), although I tend to just have a bottle or two of Tsing Tao.
As always with Chinese food, it's much better to be in a group rather than dine individually so that you get to try more dishes.
Even better if you take a short hike around Po Toi Island first to work up a appetite!
(Closed Tuesday dinner and all day Wednesday - don't go on weekends or holidays: the place gets rammed full and can't really cope.) They have a
very basic website.
