Tonkatsu and udon restaurant 2 minutes from Exit 5 in Gwanak: Kosi
Kosi Seoul National University Entrance Branch is a Sanuki udon and tonkatsu restaurant about 144m from Exit 5 of Seoul National University Entrance Station in Gwanak, Seoul, a 2–3 minute walk. Two diners ordered one tonkatsu and one udon and split them, which is the easiest way to taste both dishes in one visit. Kosi works well as a lunch stop before heading on to a café on Sharosu-gil.
