A long time ago, when I visited the first Hanamaru Udon restaurant, the Kida branch in Takamatsu City, Kagawa Prefecture, I was very impressed to meet the manager of the Kida branch, who has been there since the establishment of Hanamaru Udon, and he made udon and tempura directly for me.
The curry at Hamanaru Udon is based on the curry that this manager used to make at home.
