Udon Mandajiro is an udon shop in an alley a three-minute walk from Shinjuku-gyoemmae Station in Tokyo. It serves chewy, flat noodles, with Mandajiro Udon, On Udon, and Nikutsukemen available alongside toppings such as burdock tempura and toriten. At lunch, you register the QR code at the storefront on Line, then use the QR code on your numbered ticket to check how many parties are ahead, and the wait runs about 40 minutes to an hour. The shop seats around ten people, so the lunch wait is long and the menu is in Japanese only.
