I finally used the lounge for the first time today...and was not disappointed. It was fairly quiet when I arrived, but pretty busy when I left. I had about 4 hours, which was perfect for a first visit.
I LIKED: passport control at lounge entrance, baklava buffet, delicious manti, delicious grilled chicken and kofte, delicious Turkish delight on most of the hot drinks stations.
I DISLIKED: there being no doner kebab station. I'm sure I'd read of one. Maybe they rotate (geddit? Doner station...) the offerings or vary them over time.
Overall, I loved it. The food quality really was excellent and really tasty. I'd read a few reviews saying it is not worth the hype, but I disagree. I can't wait to see if they try to top it at the new airport.
