This restaurant never disappoints — the chicken karaage is a must-try, and the Hiroshi Tonkotsu is my favorite ramen. Service always comes with a smile.
We were craving a light broth noodle soup, and Ramen Hiroshi delivered. The yuzu ramen had a light but flavorful broth with a wonderful little pepper kick. Super friendly service — we'd come back again.
So delicious! Fast service, a spacious room with tall ceilings and floor-to-ceiling windows, and a Hiroshi Tonkotsu that hit the spot.
