SOLID 4.5 stars. Tonkotsu (or pork bone stock) ramen is the closest I've tried in Phoenix (oily - real Tonkotsu ramen is supposed to be greasy- and creamy) to what you get in its birth place Kyushu (I'm from Kyushu). Chashu pork was also on the dot, melt in you mouth tender. I had to deduct 0.5 point for the boiled egg which should have been a little more flavorful, & for ramen noodle which is little different from what I'm used to in Japan. Nevertheless highly recommended.
I'm so sad this place is far from our place :(
