The Taxi Driver - David Chiang (1975) - Peking Road, Tsim Sha Tsui

To Fat picks up a dirty old fella and his young girlfriend on Peking Road. The HK Old Mary sign you can see in the first image related to a famous shop. You can read more about it here. The Mary Building, where it was located, is still around though (71-77 Peking Road). Look carefully and you can see an advert for "Club Tasogare" (the white signboard) located in the basement (today's Delaney's).
