The Lago Marine Club was primarily for members of the Marine Department.  It was located inside the refinery, in the area of the docks and because the Marine Departments was primarily staffed by Englishmen the club was very much like an English Pub.  I remember going to the Marine Club as a child, they had a Billiards table, a bar and food could be purchased.  As with the Esso Club the Marine Club used "Club Tickets", but these were issued by the Marine Club.
