Have you ever been Korea?

 I recommend the park in Seoul the name is Nak-san Park, It was part of castles but renovated to the park, now we can use by shelter. It has little bit high ground as protect the city. You can get some information how about Korean University students since there are located in between a lot of universities; so many students visit there in springs and falls when weather is warm. Maybe they are getting some drink there. As it takes 20 minutes to the top of the park, you should have your meals a lots and go there. Although It's takes long time, you never regret when you reach in the  top of the park, as you can see the great night views in the Seoul. it is really impressive. and I said before the park is close the universities, there has a lot of restaurants, and store, theater. you can go anywhere if you want!
