Butanomax is a Japanese ramen shop near Gangnam-gu Office Station in Nonhyeon-dong, Seoul. It focuses on iekei ramen and rich tonkotsu ramen, with a deep pork-bone broth topped with two large pieces of chashu. The menu changes by season, and during the miso ramen period it comes with ginger aroma, menma, and flat noodles mixed with medium-thick noodles. The smell of the cloth being wiped nearby rises into the food.
