Also, the Daejeon International Community Center offers classes for Foreigners at a range of different times. I have just finished their evening classes and have found myself a friend of a friend to tutor me.
So check out their website for more information on their classes. They are held at the Community Center which in opposite the Daejeon Station, and cost about W5 000 for a 20 week course, and you will need to buy the textbook too (W14 000). All in all a very worthwhile course to do, and the Teachers are super nice :)
