Wonjo Gisanim Bunsik sits right next to Exit 2 of Daeheung Station in Seoul and serves jajangmyeon, jajangbap and udon in the style of a drivers' restaurant. The jajang is the savory old-fashioned kind rather than the sweet Chinese-restaurant version, and the jajangbap comes with a fried egg, seokbakji kimchi and udon broth. It stays open until 3 a.m. and the food comes out quickly, so it works for a late stop. The flavors are not strong, so high expectations can leave the meal feeling plain.
