GangNam Spa is more than 30,000 square feet, all dedicated to self care. The idea is to use natural beauty methods, instead of relying on chemicals. That means a lot of exfoliation and both hot and cold therapy. Some of the rooms are as hot at 150 degrees! You might be there for a while. Many of the beauty services take hours to complete. Don't worry, though - there's a full service cafeteria if you get hungry. It's a social event: Bring your friends and family, and don't be surprised if others do, too.
