Jo and I have lived in the outskirts of Seoul for nearly five years. During that time, we’ve seen this one cafe pass us by as we cross the Han River while traveling over the Hannam Bridge. It took us a while, but we finally managed to get off a bus and check it out.
I will say that the views from the cafe are great, but inside, there’s no air conditioning. The day we went, it was nearly 30C (86F) outside, so indoors it was considerably hotter. With no fans or moving air, it was just too unbearable to remain there. It’s a pity, since the views were grand.
Overall, not being able to remain inside was a bit of a disappointment, but certainly has sparked my desire to return in the fall/winter.
To get there, just take any of the blue trunk buses that cross the Hannam Bridge. On the route, make sure they stop at the cafe. The bus stop ID is 23-531 (한남대교전망커페) and buses 140, 142, 144, 241, 400, 402, 407, 408, 420, 421, 470, 471, 472, and 3011 stop there.
