I make a really bad cafe reviewer simply because I drink neither coffee nor tea, but Haru & One Day (celebrity owned cafe by Lee Dong Hae, Super Junior) is one of my favourite cafes to go to every time I’m in the area. My favourite drink here is (no surprise) the green grape juice, and the cheese cake’s decent although a friend says it could be better. More than anything, I love the interior design and how uncrowded it is most of the time. Being less than a hundred metre away from Exit 4 of Seongsu station, it’s very accessible, making it an ideal place to do your work.
