Solid four star for me after trying here once.
Tried their tonkotsu ramen and it is not like traditional tonkotsu ramen you might get in Kyushu Japan, but flavor is defiantly good, I still enjoyed it. Flavor is very similar to miso ramen you might get in Japan. Noodle they used was thick version, often served with shio or miso ramen. Noodle was cooked perfect, I enjoyed the texture. Although I liked their broth, it would have been better if soup was hotter (temperature hot). If I am in the area, I would ask my broth to be really hot next time.
Gyoza was served with hot dipping sauce. It wasn't my favorite kind.
I tasted gyudon and flavored well. I also tasted tempura and thought could improve tempura batter.
Service was good, even a chef came out and asked if everything was good. It seemed like a lot of regular there when I visited. I would come back again if I am in the area
