And also, I wouldn’t stress about the difference between the two lounges. They are broadly similar, just with a slightly larger buffet and a little more capacity in one, but you won’t be missing out on any particular amenity by choosing one over the other and the decor is basically identical. Use whichever is more convenient for your flights’ gate assignment.

ICN T2 is a pretty low stress airport - it’s not like HKG where picking the wrong lounge means a dramatically different airport experience. Most of the gates and most of the lounges offer a broadly similar experience.
