Our Seoul-Incheon connection was too short to go to a lounge. We still made it to the Sky Hub Lounge. Now they have DIY bibimbap! Time was so short I couldn’t even partake.
The twin Sky Hub lounges in the main terminal upper level, one near the Asiana transit desk, one near the Korean Air transit desk, and accessible with Priority Pass and Diners Club, have basic amenities to go with great food. Get your bulgogi, tofu, and if in season, you might find rambutans! Some local drinks and the ice cream have been scaled back, otherwise Sky Hub is humming along.
Contrast with the Asiana (accessible with Priority Pass) and Korean Air lounges which are disappointing food-wise. Both have generic international food. I only swing through Korean Air for the day’s papers and ginseng tea packets.
When connecting in ICN, find Sky Hub and feast.
