Krug Room, Mandarin Hotel Hong Kong
When it first opened, there was only the tasting menu, although they would personalise it for you. Now you no longer have to book out the whole room, you can just book places in it for round HK$2500 per head. There are various food options but you need to ask the mandarin for details.
The room itself is good though, big window on to the kitchen and all the wood is from kug casks.
