I love Shinsegae (supposedly the world’s biggest mall). If anyone ever wants to go there, I am game, because I still have not explored every crevice. And, oh yes, I have tried —and will continue to try!
I have only watched movies in Korea at the top floor of Shinsegae. I must say that it is amazing! The only tip I can tell is not to watch any animated or kids’ movies, because they’re usually dubbed in Korean. Unless you like that sort of thing.
