Chungking Mansions (重慶大廈)
17-storey composite building at 36-44 Nathan Road, Tsim Sha Tsui, completed 1961. Budget guesthouses, South Asian and African restaurants, currency exchanges, and wholesale shops serving people of ~120 nationalities. Featured in Wong Kar-wai's Chungking Express.
The closest thing left to KWC's vibe — hyperdense, multi-ethnic, slightly lawless tenement. South Asian/African guesthouses, food courts, money-changers, currency arbitrage. Wong Kar-wai's 'Chungking Express' building. Walk in, get curry on the 7th floor, do not stay overnight unless committed to the bit.
