The Korean Air Prestige lounges in T2 are much better than the old ones in T1 and the Concourse. Food is improved and one can actually make a decent meal. Alcohol appears to be the same, I like the Ballantine's scotch.

B/t/w/ I think Korean Air only has lounges in T2 now since that is where its operations are located..
