Iroha's unusual, very original take on the standard udon noodle includes Italian-themed variations such as eggplant and bacon in spicy tomato sauce and Udon alle Vongole with clams and zucchini. Other popular options include a beef-curry udon and avocado-shrimp udon in a Japanese-style cream sauce. Most bowls are priced in the Y880-1080 range.
