PAPA Board is located in Changwon in the South of South Korea.
It looks like they take the cafe side of the board game cafe part very seriously and it seems a nice place to play.
As you can see they have a LOT of plastic hammers and are clearly worth a visit if you are in the area.
I have never been there though and can't offer much advice on how to even find the place. According to their directions they are very close to the South East corner big intersection/rotary in the middle of this map.
If you are near Changwon I would seek out t a little more information before trying to find this place. Hopefully they show up on Wizards store locator soon.
