This is one of those spots you shouldn't go out of your way to visit, but if you happen to be nearby, you'll find a reliably good meal. It reminds me more of a school canteen, with its standardized, self-service approach. The menu offers a decent variety of classic Korean dishes (gimbab, ramyeon, tteokbokki, etc), all at a reasonable price. I particularly appreciate that they're open 24 hours, making it an excellent supper spot, especially if you're staying in the Myeongdong area.
