hmm, 36 hours. The food i like best in Seoul are the beef. Fresh beef for korean barbeque. There are a number of good restaurants and the one I like most is called Pak Dae Gam Ne. If you show it to a hotel, they should know. A pretty local place but decent service. Some of the freshest and tastiest beef I have ever had. Unlike Japanese beef which is fatty but without taste, Korean beef has both.
