I had a few hours at ICN this week. Picked the lounge by Gate 281, and it was totally worth the walk.

Morning flight, lounge was empty (so was that whole wing of the terminal).
Food was better than I recall last time.

And the outdoor situation with the little temple and bamboo forrest = easily the coolest thing I've seen in any airport, ever.
Just being outdoors, in some fresh air, while inside the airport.
Amazing
