I have been in both the 2F and 2E lounges. To be honest, I am not as wild about AF lounges as others are. I do agree that AF seem spacious, but I didn't see that many people in it period. One thing they do that is wise is have to lounges (L and R from entrance desk, they are the same as far as I can tell).

I find the good OK, coffee good, drinks average. I find BA offers a better lounge.

My main issue with AF lounge in CDG is that it is in the basement, so you can't see anything.
