Until the new TK lounge opened the catering selection was virtually identical at every single lounge in IST. Now that TK and Do&Co have incredibly significantly raised the bar (not only in Istanbul, but globally) the Millenium lounge has a slight edge over the others as they are in fact doing a small selection of hot and nicer food around meal times at least. Also, they have added Coke in glass bottles, a huge thing for those of us who remember how crap their fountain sodas taste.
