The noodles are straighter and longer, thicker, and more chewy. The catchphrase is "Beppin Udon." [For Eastern Japan]
The chewy and smooth Donbei are topped with a deep-flavored soup made from a flavorful dashi stock made from bonito and kelp, and a rich soy sauce. Attached is a spicy "colorful shichimi" seasoning made with red chili peppers that enhances the flavor of the soy sauce.
