Koei-ken
Founded in 1977, this legendary town Chinese restaurant near Arakawa Ward Office has stood for over 47 years. The mega-size fried rice (5 cups of rice, ¥1,200) is hailed as the king of mega-portions in Arakawa. Its light oil, mild seasoning, and surprisingly smooth texture are signs of true craftsmanship. 200 customers a day, with 2nd and 3rd-generation regulars — a genuine local institution. The karaage is also exceptional, drawing visitors from across Japan via Google Maps.
