Golgo 13: Assignment Kowloon - Sonny Chiba (1977) - Repulse Bay Hotel, Repulse Bay

There is a brief scene that appears to have been filmed in the garden of The Repulse Bay Hotel as Golgo's rather pompous British client talks to him about his predicament. Pity we don't get to see the rest of the building, but perhaps it was filmed without permission?
