Well, technically, this post should be Middle Road Children's playground: however, as Phil from the highly recommended Hong Kong (& Macau) Stuff / Hong Kong (& Macau) Film Stuff blogs points out, this spot has been raised twenty feet upwards with the construction of the East Tsim Sha Tsui MTR station.
Still, the Mariner's Club, shown from the playground side in the screen cap, is still there, in one piece and very recognisable.
