Ryukyu Shinmen Tondou is an Okinawa ramen shop in Naha, a three-minute walk from Oroku Station and one minute from Aeon Mall. It serves tonkotsu ramen with a rich pork bone broth and a salt ramen made with chicken broth. Orders are placed at a vending machine, and choosing a kids' menu comes with a toy. Chilled green tea is available, and payment is cash only.
