Re: UK English and "pub", "bar", "saloon".
Colloquially, the "bar" is used to mean the place where the drinks are served. So, when in the "pub", we would say "I'm going to the bar" to mean that we're going to get more drinks (having drinks brought to your table is very rare here.) "Bar" for the building itself has become more common, though - to begin with, often a drinking place which had some kind of "exotic, foreign theme", or a drinking place in a building not originally designed to be a pub (e.g. a hotel or sports club.) "Saloon" is still sometimes seen too, to mean a quieter room in the pub where you can sit in comfy chairs, separated from the serving area. In older times, the "saloon" or "lounge" often had the connotation of being the part of the pub where it was acceptable for women to drink, as opposed to the "tap room" (containing the bar) where it was considered only appropriate for the men to drink. Most pubs are open-plan these days, so those separations are much less common than they used to be.
