L'Inconnue de Hong Kong - Dalida (1963) - Pilkem Street, Kwun Chung

Whilst the girls are performing at the night club, they are accommodated in a hotel called the Honor Hotel. It turns out to have been a real place and was located at the Austin Road end of Pilkem Street (where the Pilkem Commercial Centre now stands). Most people call this area Jordan after the nearby MTR station, but actually it's proper name is Kwun Chung. The hotel appears to have a fair amount of sordid history according to the blurb that is attached to this video of it on Youtube.
