Hoho Myoll Cafe in Hongdae, near Sangsu Station...randomly fell upon this cafe with a Volkswagen camper inside! They seem to be pretty serious about their coffee, and their warm apple tea is a definite winner!
Just wanted to post a few photos...that's all:)
Sangsu station (line 6), exit 2 in Hongdae
Walk a few blocks, cafe will be on your right
