Huwahuwa is a Japanese-style tonkatsu restaurant in the food alley of Jongno 5-ga, serving thin tonkatsu in a light Western style. The menu includes a tonkatsu set meal, cheese tonkatsu, and hirekatsu. On weekday lunchtimes there is a long wait, and the hirekatsu sells out early, running out even by noon. The rice comes in a small scoop, so the portion is on the small side.
