Take a ferry to Lantau Island and go to Po Lin to see Big Buddha - ride the tram though Central - take the Peak Tram - Go to Temple Street night Market (north-west of Nathan Road, TST) - If you are a Bond fan (and male) go to the Bottoms Up club in TST, just north of the Star Ferry terminal in TST, opposite HMV - have proper dim-sum - The Bull and Bear below the Bank of America Building does good UK food if your stomach is not up to the job of real chinese food - I lived in HK for three years and never saw it all but those are the touristy bits.
Hmmmm, getting teary eyed and nostalgic now.
