AF lounge in NRT is the worse I have visited, JNB comes quite close too. Both are "new design lounge", very hard and uncomfortable seats, not possible to do anything as the "table" linked to the seat is very small, non practical and unstable since the seat itself is not perfectly stable: I would not put a glass of coke on it! spirits are mainly bad quality ones, snacks are on par with domestic AF flights, no urinal in men toilet, non working wifi... the only positive point is the beer machine that is fun
I was happy to take the JAL codeshare from NRT to CDG, got AF miles but much better lounge, not talking about onboard service.
