Kyokoko Sinnonhyeon serves Japanese dishes including ramen, oyakodon, and steak near Sinnonhyeon Station in Seoul. The shio-tori ramen comes with a spicy, clean-tasting broth, and the oyakodon is a rice bowl with plenty of chicken. The steak is served medium by default, with garlic and butter notes that go with rice. Without a reservation, there is a wait.
