MMMG Cafe in Insadong is sooo cute^^
Here you are clearly paying for the atmosphere and if you want to be in an environment of cute, this is the place to go. Alright, I know it's not the manliest place, but I like to hang out there and get a cup of coffee and get some writing done.
Oh wait, there's more. You can even shop for cool stickers, bags and other unique stuff.
