IN TOWN last week was Oliver Stone, a regular visitor who sticks to a well-worn path whenever he's here. It basically goes from Kai Tak to the Grand Hyatt and involves a visit to Lan Kwai Fong where California tends to be the club of choice. On his latest visit, the Natural Born Killers' director dined at Grissini with local movie industry connections and showed a refreshing lack of interest in Planet Hollywood.
