Chottonkotsu Noudo 8 Ramen in Osaka serves thick tonkotsu ramen. It offers the standard 8 Ramen and the limited-quantity 27 Ramen, whose pork broth is especially rich and thick. The shop has only 10 seats, so waits run 10 to 20 minutes. Orders are placed at a Japanese-language ticket machine, which is difficult for first-time visitors.
