This is a renowned Japanese restaurant famous for its donburi and katsu, which always has a queue during meal times even on weekdays. The signature dish is seasoned donburi grilled on an iron plate, which is incredibly delicious. Additionally, their katsu dishes are a perfect example of "gatsubara-sokchok"—moist inside and crispy outside. I believe this is a Japanese katsu restaurant worth visiting during off-peak hours to avoid the long lines. ^^
