Visited the lounge this morning. When I got there around 4:55am there were something like 5 other people in front of me. Maybe another 5 or so got behind me by the time they started letting people in, so not too busy.
Anyway, (a) I was totally paying attention to the wrong part of T2 during construction and (b) the breakfast they had was pretty good:
Wish I could have stayed a bit longer than a half hour but it definitely took long enough to walk back to the farthest AS/AA gates in T2E from the lounge that I wouldn't have wanted to risk it.
