We went to a club in Hongdae where you can dance ankle-deep in water. The whole place looks like someone realized their fantasy-club without any regard to practicalities or safety standards. The result is awesome if somewhat perilous.
Nevertheless, while I did some careful semi-dancing, a rowdy teenage bunch took to the floor, splashing with abandon and jumping recklessly on each other. No fear.
It's called Bar Oi and is about 2 minutes from the park in Hongdae. Not really a happening place, but the novelty's good for that 3am denouement.
Oh, Oi, I know it. Stumbled in there solo around 3am on Saturday for a break from the awful Cocoon. Just saw a few guys packing the chairs away.
