Kirimugiya Jinroku is an udon and fried food shop near Shinjuku Gyoen and Shinano-machi in Tokyo. It serves udon and chicken breast tempura, and the tempura is tasty but the portion is small. Even entering first at the 5:30 AM opening, food takes 20 minutes to come out, and customers wait before being seated. The shop is small and the udon taste is ordinary, not special.
