Day 1: KT&G Sangsang Madang A Beautiful Mess Lifestyle Shop and Art Museum - Hongdae, Seoul

First 2 floors is a shop selling all sorts of artsy home ware that you probably don't need, but really cool to have.  Some of them are not that expensive either~.

Then the top 2 floors are gallery.  Free admission.  At least it was free at the time I visited.

 KT&G Sangsang Madang is at point x in Places Part 4 on the map below:
