HK abt 1916.jpg

If you zoom in above the head of the man at the left of the front row, a sign above the doorway looks to read:

HK PRC
PRIVATE
????????

Which would confirm it as a photo of the Police Recreation Club.

Do you recognise any of the people shown?

The smaller words below the PRIVATE may be something like 'For members only'?

Perhaps the view at https://gwulo.com/atom/15005 can confirm.

Moddsey's link is the confirmation. The tall building with the three arches, in the background above, is just above half-way down the left side of this photo:

The PRC was demolished in 1919 and a new building erected on the same site. The new club was opened on the 2nd May 1919 by the Officer Administering the Government, Claude Severn, in the absence of the Governor, Sir Henry May, who was Captain Superintendent of Police from 1893 to 1901.
