If you can't speak Korean well, you should go to Daechi Juno and ask for Ji Woon(지운)~ He speaks English well and he will provide you with excellent service. He has a good sense of humor so I always have fun when I go there. He's the guy with the cool samurai hair, you can't miss him. Every member of the staff is nice and friendly as well (they'll try their best to speak English ^^).I would highly recommend them for foreigners in that area, especially those of you who teach in Daechi( I know there are a lot of you since I am one myself)! Ask for JiWoon shiljangneem (지운실장님)!
