At HiroNori Craft Ramen in Hillcrest, the tonkotsu ramen features a creamy pork broth, thin noodles, chashu, kikurage mushrooms, and green onions, often with a marinated egg added. The kitchen emphasizes a deeply flavored, slightly thicker broth and a restrained topping set that keeps the focus on the soup and noodles. Each bite alternates between the lush broth, the chew of the noodles, and the tender pork, with the egg adding extra richness. Ramen guides consistently highlight HiroNori’s tonkotsu as one of the most carefully executed bowls in San Diego’s ramen scene.
