Can some of you professionals help me make a 3-4day plan in Seoul Korea most of them are at or near Dongdaemun area? I don't really want to see museums cause I've watched all Running Man eps Lol if you watch this show u know what I'm talking about Lol but I've very interested to see at least one traditional Korean place and I would like to find a photo place where I can try out their traditional clothing and take photos =] BBQ is a must cause Korea is famous for it and of course street food street food and more street food. Amusement parks? I'll p cause my country has those sort of things too but ummm I dunno It's Gonna be Fun! Can you guys help me??? Thx ^^
