The sauna is called Itaewan Land. It is nice inside. Separated male/female showers, hot tubs, cold tubs, herbal tubs, steam room. Co-ed saunas, including a cold sauna. Small restaurant in the co-ed area to get something to eat. Don't have to have won there, they charge to your locker key. You pay when you exit if you bought something inside. They just started massages. Did not try for happy ending, so don't know if it is available.
