Kirinya Honmachihonten is an udon shop in the office district within walking distance of Honmachi Station in Osaka. Bowls come with chewy noodles and toppings such as raw egg, onsen egg, and fried items. The shop opens at 7 a.m. and uses a prepaid self-service system where customers order first and pick up their food when it is called. There are no tables, so the shop is a standing-only space.
