I've been in Hong Kong. In Central just down from my mates flat we saw a sign saying 'best coffee in town'.
It was coming from this place called Eat Right.
To get there just ride the Mid-Levels escalator up to Staunton street and then back down a couple of doors.
Its a 'health food' (*shudder*) restaurant but don't let that put you off. I don't know what kind of beans they use but they are from 'Toby's Estate' in Australia. The young barista guy was really into doing a good job for us. Once he knew we were in there for his coffee he was great and came out to check with us that all was well with our double espressos. And all was well every time we went there. If you can't face having a healthy breakfast then you can get huge fryups with beer 24 hours a day round at the Flying Pan on Elgin street and then get a decent coffeee at Eat Right. If anyone else knows anywhere good in HK please reply as I'd like to go back there.
