I had a Korean Hot Spring Bath yesterday. I feel completely relaxed now. You have to have Absolutely no body issues, and walk around stark naked once you get into the women's room.
You feel like a baby being scrubbed because there are these massage beds covered in plastic sheeting, and you lie on them whilst a plump Korean lady in her underwear will massage you with what looks like Brillo Pads! Then slather you with soap and splash alternating hot and cold water your tingling skin.
It's great, and you pay about only 18 USD for the experience. Nobody speaks English so you have to get by with alot of finger-pointing and "sorry-i-am-an-idiot-foreigner" grins.
