The cafe Donghae & Eunhyuk went and played with a dog (I don't think they air this in the show itself, only in the behind the scene of the show) Video link: https://www.youtube.com/watch?v=c1tRH7PIIaM

P.s. This a cafe for many show/magazine shooting, they were filming some kind of game show when I went there for the first time. TVXQ's Humanoids album photos were taken here too.
P.p.s. They have a dog call Seoul (the one in the video) but she wasn't there when I was there :/
