This popular restaurant is renowned for its chemical-free soup. the soup is made by thoroughly simmering chicken, knuckle bones, seafood, and aromatic vegetables, creating an exquisite umami flavor that is a balance of richness and lightness. it goes perfectly with the flavorful homemade noodles, which are a blend of stone-ground flour and domestic wheat. you can enjoy a variety of ramen, including the standard "tenko ramen," "kuro tenko," which has a prominent flavor of burnt garlic oil, and the deliciously spicy "aka tenko," which has a touch of chili pepper added to the homemade chili oil.
