This is still a three-room pub, with all three rooms having their own door to the outside. The rooms are interconnected by open doorways - i.e. openings where doors used to be. The room on the left could be regarded as the public, or perhaps sports, bar as it contains a pool table and dartboard; it's furnished with dark varnished tables and normal chairs. The centre room is the smallest of the three, but still too large to be a jug & bottle bar I would think (snug possibly?). It is small enough that it contains just a couple of tall tables/tall stools. The room on the right would perhaps have been the saloon bar. The button upholstered bar counter front gave the room a 70s feel.
