A new hip place where you can go for classic European style light meal (Rose Bakery) and find something expensive for no reason (Comme des Garçons flagship store).
Rose Bakery is reasonably priced, a coffee for 7000 won, a carrot cake 8000 won. Light meals around 13000 won. I especially recommend carrot cake and cheese scone. Their light meals and latte do not wow me, but their Americano is supremo...ly strong. Worth trying!
Rose Bakery X Comme des Garçons flagship store:
Subway Line No.6, Hangangjin Station Exit 1, walk 3 mins.
( Note to those tight with schedule: This fact may help you prioritize your schedule - there's nothing interesting to see in that neighborhood, except Samsung Leeum Museum. )
