I always go to Jeju Island. I think this is the most authentic one. It used to be run by a few old ladies. This time, the boss seems to have changed. None of the old ladies are there. There is a waitress who speaks Chinese. The lady is so nice. She gave us two side dishes and is very friendly to Chinese people. The taste of the potato pot has not changed. It is still so delicious. We chose this restaurant for our first meal on the first day and the last meal before going to the airport.
