Well-- I think that woudl be backwards, really. The biggest and most defining 'piece' of furniture in the room will be the bar and the shelfing behind the bar. I think the most logical place to start if you're trying to capture a look is to decide about the bar area first.
Nailing down how big the bar will be, what colors, where it will go and what the styling is will help define the limits for the rest of the room. For example--- if you go with one of the black/brown 'guiness pub' looks that is all teh rage in the US, that will result in a very different look than going for the rustic 'This pub has been around since the middle ages' look which would indicate a more 'plain plank' bar top or you could aim at the 'gentleman's pub' kind of look which might contraindicate a 'real' bar at all and have more of a counter on a wall with the offerings.
How that bar looks is a big part of what your end result will be.
