Onsen Cheonan Branch is a tendon restaurant next to Cheonan Express Bus Terminal. Order the Japanese-style fried rice bowl and the tempura is fried in the machine in front of you and placed directly on the rice. On weekend openings, write your name in the notebook to the right of the door and wait, and take pickled radish, pickled ginger, and kimchi from the self-service corner. Cooking takes a long time and the amount of rice is on the small side.
