Ginza Soba Shiraseki is a 24-hour noodle shop in Roppongi serving soba and udon. Its soba has a high buckwheat content and breaks apart easily, while the udon noodles are chewy and firm. Orders are placed at a kiosk, and the receipt is handed to staff, who then boil the noodles, so preparation takes a little time. The menu also includes sweet shrimp rice bowl and mentaiko cream udon.
