Are you Planning to visit Korea?
I've made plans for you. If you want, I'll give you a tour.
On the first day, We'll go to insa-dong or samchung-dong which is famous for korean traditional mood. You can many houses that was built in traditional way. You can visit palace, too. I saw many foreigners have interest in korean palace you can try traditional clothe(s?) that is called "Han bok"
On the second day, I'll take you to Myeond-dong. It is very crowded because there are many shopping malls and restaurants. It is located almost in the middle of Seoul. You can see many asian people there they go myeong-dong for buying cosmetics.
On last day, we can go to coex-mall. It's huge multi-plex located in Gang-nam. It has Theater that has big screen and Aquarium. You can enjoy various fishes in Aquarium. If you want , I can take you to restaurant that serves menu you like. Hope you like my plans !
