Excellent train station, large, there are signs, shops, cafes 6a of different tastes, the staff is responsive, they helped to buy tickets at the vending machine.
Good staff, they helped me with the translator.
Cheeto, there are many shops and eateries. There are self-service terminals, if you have cash, go to a live employee.
I don't know what else to say, if you are in Korea, it is better to use Kakaomap rather than a Google map, since it works better in Korea. For a Kakao T taxi, it is cheap to pay in cash, cheaper than looking on the street + foreigners can be thrown.
Ps. Do not touch other people's things and do not quarrel with Koreans. They can just shrapnel you , or else deprive you of your freedom
Ps.2 do not go to the local burger King at the station, the staff is bad. I said not to make it spicy, but put a cap on it like a spicy burger, although there may have been a problem with the translation
