take him on a tour:
41 Cumberland Road, Kowloon Tong - Bruce Lee's old house, then subsequently owned by another chop sockey star called Alexander Fu Sheng (he was killed in a car crash on Clearwater Bay Road back in the 80's - hence why people consider the house to have VERY BAD fung shui). It's now a love motel so I doubt you will get in unless you want to book a room ;-)
Beacon Hill, there are some aprtments there where Betty Ting Pei used to live and where Bruce supposedly copped it. Sorry don't know exact address, may be worth googling. He was taken to Queen Elizabeth hospital in Kowloon when he died.
Film City in Clearwater Bay - is it still open, I think so?. But basically any HK made Kung Fu film from the last few decades would have had at least some (if not all) of its scenes shot there.
Tai Tam Bay - where Enter The Dragon was mainly filmed.
Aberdeen Harbour, had some shots from ETD, if you watch the film you can see the old power station which was to become South Horizons on Ap Lei Chau.
45 Stubbs Road - used for a long shot of Han's palace in ETD (amongst other films)
There's loads of locations, shame the Govt doesn't make more of it as a tourist thing, they only have the really tacky Avenue of Stars down on TST harbour front (you will definitely get Bruce Lee memorabilia there, but it may cost more than you need to pay) which is really forgettable, apart of course from the Bruce Lee statue outside Pacific Coffee.
