Katsumiya
A popular udon shop near Tosu Station with regular lines. The specialty 'Sudori Kamatama' (named with 'Tosu' in reverse) is made by cooking fresh-made noodles in a pressure cooker per order, topped with sweet-soy chicken skin. The chewy noodles and rich sweet-soy glaze are a perfect match. Called 'a restaurant to preserve for future generations' in local food blogs.
