Also, does anyone have any information about life in Jeju-do?

Basically, I'm more interested in a decent expat English-speaking community (comforts of home, I suppose), a decent nightlife (going out every now and then), etc etc. From my research, the scenery should be amazing (black sand beach? hello?) and google had a bit about casinos. But besides that, I don't see much else posted...

If it helps, I'm an unattached (read single) 25/male.

Thanks in advance...?!
