Have a look at our Areas and Suburbs in Hong Kong page which gives a good overview of suburbs that are popular with expats. I think you may be thinking of Kowloon but Hong Kong Island also has a number of hills. The page gives a good breakdown of a number of areas that are popular with expats, and should be worth a look.
Central, Hong Kong is the best! It is home of Lan Kwai Fong which is the center of clubbing in Hong Kong. You'll find great restaurants deals there. Lounges abound and the coolest bars are everywhere. My favorite one is Play club Asia because of its spacious dance floor.
