It is barely a restaurant - a marble counter with about eighteen stools, no tables, no kitchen to speak of - and has been run by the same family for generations, serving the same short list of cold shellfish.

FIBIwiki's history of the station states the new building "was brought into service on 1 December 1905," a specific documented date independent of the documentary.[1]
The East Indian Railway brought its new Howrah terminus, designed by Halsey Ricardo, into service across the Hooghly from Kolkata, replacing the original 1854 station building. Its North Wing's six platforms were built to absorb traffic that had grown sharply since the Bengal-Nagpur Railway opened its Calcutta Extension Line into Howrah in 1900.
