My locals in the 50's were the Vernon & the Highbury. Your list is pretty comprehensive and I'm struggling to add to it. Additional memories though are of the cinema manager shutting down the projector, turning on the lights and threatening to throw everyone out if we didn't "shurrup and stop messin' about". Then there were the sherbert dabs bought on the "walk" to the matinee. We must have been a pretty smelly lot - especially if we'd come in from the rain.
