ASIANA BUSINESS LOUNGE! Depending on the time, it can be very spacious with two large sections. Plus they have nice showers, that I try to take advantage of every time I have a layover there. Food is decent, big TVs (usually showing golf), lots of desks, plugs and comfortable chairs. Of the dozen or so stops I've made to that lounge, I think it was crowded (still found open seats) one time. Every other time has been at ~10% capacity.
