This series is fantastic and anyone interested in seeing different food items/restaurant scenes in both Korea and Japan, I highly recommend watching the series. The two men try to show their favorite eating places in both counties. They also have very good rapport. It is in season 2 now, but I hope they keep doing more. There are english subtitles.
I was recently reintroduced to mul naengmyeon and I am a big fan of it. The first time I had it years ago ago and was not impressed but now, I can't wait to visit S Korea for this dish. They go to a resaurant specialzing it.
