I think the bar is just too big, especially the area behind the bar. Typically only one or two people behind the bar and wasted floorspace. I have an L-shaped bar the seats 3 on one side and 2 on the other. Very similar to your layout. You will need much more traffic aisle way to get from room to room. I recommend shortening the leg of the bar on the pool table side and do away with the 45 degree portion. Just take it straight back.
