Sanpoutei Ramen is a ramen shop in Singapore that serves tonkotsu ramen and tsukemen. The tonkotsu broth is rich, the chashu is soft, and the noodles come out chewy. On Sundays, customers wait before opening, and families are guided to seats that resemble semi-private rooms. Ordered onigiri or green tea has been missed, and customers who arrived later have been guided in first.
