The secret behind the popularity of this Tonkotsu ramen house in Moiliili is in its slow-cooked pork broth, which is topped with black garlic oil and crispy garlic chips, giving the succulent meat even bolder flavor. A low-key local chain, it offers more than 15 varieties of ramen -- from chicken to vegetarian to pork -- and they all hit the mark, particularly specialties like the Char Siu Tonkotsu: a heaping bowl of thinly sliced house char siu, shio ramen, and a mountain of your choice of negi, zaasai, or spicy kimchi.
