Marugame Seimen Namba

Marugame Seimen Namba is a self-service Japanese restaurant in Namba that serves udon and tempura. The udon noodles are chewy, and a self-service bar lets diners add green onions, broth, tempura flakes and kelp. A small Korean menu is posted at the entrance, and diners line up to choose udon and tempura before paying. The ordering process can be cumbersome for those unfamiliar with it.
