Choi Oi Noodle is a Japanese ramen shop in District 1, Ho Chi Minh City, serving tonkotsu ramen and tantanmen. Its signature Cappuccino Tonkotsu Ramen comes with a rich soy-based broth topped with soft cream foam, and the tantanmen is ordered by choosing a spice level. At lunch the shop fills up, and the open-bar layout puts the cooking area in view. The tonkotsu ramen contains thick slices of pork, and the seating is narrow enough that noise from the next table is loud.
