Heosuabi is a Japanese tonkatsu restaurant on the second floor of a building across from Munhwa-ui Geori, a five-minute walk from Nowon Station in Seoul. It serves anshim kaseu, hire kaseu, and saengseon kaseu, with ground sesame seeds that diners mix into the sauce for dipping. Rice and kkakdugi come with the meal, and the anshim and hire kaseu have a soft texture. Ventilation is poor, so the dining room smells of oil.
