Kanda Soba Hyehwa is a Japanese ramen restaurant in Daehak-ro, Hyehwa-dong, Jongno-gu, Seoul, serving tonkotsu ramen, mazesoba and aburasoba. The mazesoba combines 62 ingredients including egg, vegetables and meat, and is finished by adding vinegar or mixing in rice. Customers order and pay before waiting outside, and the line moves quickly because there are many seats. The ramen and soba are thick and oily overall, so eating them without a drink becomes tiring.
