Machida Shoten Japanese Ramen - Hai Bà Trưng is a Japanese ramen shop in central District 1, Ho Chi Minh, serving Yokohama iekei ramen along with tonkotsu, miso, and tsukemen. The tonkotsu ramen has a rich pork bone broth, with chashu and soft soy-marinated soft-boiled egg. When ordering, you choose the noodle thickness, noodle doneness, broth salt level, and amount of chicken oil. The broth is on the salty side, so ordering a lower salt level the first time is better.
