Personally around the holidays I am a sucker for kourabiedes - especially when freshly made. My inlaws actually prepare them with olive oil instead of butter (its a Peloponnese thing) and that makes them (sort of) healthy. Its my excuse to eat tons
Havent seen kourabiedes at any lounge yet though.
As for savoury treats the Goldair lounge is not bad, although it would be nice if they could serve the pasteries hot. Have to say that I kind of like the salad option that most lounges offer now as well. Sure those tomatoes have been sitting there for a while, but overall I find a hearty tomato, cucumber, red onion (Hello seat neighbour
) & feta cheese bowl very satisfying before a flight. Too bad none of them offers any great bread to accompany a salad!
