The one time I visited the KE lounge it was very old and hmm similar quality to mainland Chinese carriers. China airlines was quite good for emerald and paragon members with their own special little first class room (16 seats I think?) and you could order a number of decent dishes from a menu. Business class was well slightly better than KE but only just and the food options sucked. Air France lounge was actually quite decent and definitely my favorite if I wanted to see the planes plus it had a shower where the other 2 lounges didn't have.
I do miss those days, however I do also like the Skyteam lounge which is an overall improvement for all business class passengers. Just it is a shame there is little view outside. Plus the lounge often gets quite busy so I could definitely see it getting too busy in the next couple of years as the general trend is for increasing numbers of flights to and from HKG. So they definitely could have tried in getting a slightly bigger size to accommodate future growth.
