Udon Iroha is in Jingumae, Shibuya, Tokyo, near the busy area between Harajuku and Omotesando. It serves fusion udon and udon-noodle pasta, including curry udon, carbonara udon, and mentaiko cream udon. At lunch, one item from salad, rice, or a drink is included at no charge. A wait forms at lunch, but the table turnover is faster than at other places, and the wait grows longer during hours when tourists crowd in.
