The above sign, date unknown, obviously from the Charington brewery, but where was the pub?

Above picture sent to be from Paul Watson who says the following:- "Just watched episode 6 of a 1980 TV series called Fox. There's a scene in a disco and when characters leave it can be seen to be called "Al Jolson's Atlantis Disco".

Makes me wonder whether this was inside the "Dreamland" complex.
