Eun-pha Piano –> Felt Coffee (펠트커피) in Hongdae
Felt Coffee is a roaster coffee shop with a private piano school sign board in Hongdae. If you didn’t know it was there you would probably just walk on by. Or more embarrassingly, go inside expecting to get your kid (or yourself) some private piano lessons and look around stunned. Um, where are the pianos? At least you can play it off by buying a cup.
