I had a chance to visit the E lounge earlier this week, before BA164. I can't say it's nicer than the old lounges, but it's different, which is refreshing. There's a bar at one end with some drinks, a nice change to the closet hiding the hard stuff in B and C. Having said that, the lounge was packed. I don't think there was a single available seat about 90 minutes before the flight. Appalling.
