Ibuki Udon Tokyo Midtown is an udon shop in the basement food court of Tokyo Midtown in Roppongi. Its signature iriko set comes with cold or hot noodles, iriko sauce, iriko tempura, and iriko rice. On a weekday lunch around noon, the wait was three minutes before entering, and a noodle size upgrade is free. The iriko broth and sauce have a strong fishy taste.
