I'm from Japan. This review is the view from the native Japanese person.
The presentation of the ramen is probably the best in Arizona. It looked really close to what I usually see in Japan. However, the flavor is weak. Especially, the soup of Tonkotsu ramen was very weak. Tonkotsu soup should be thick and strong.
Of course it's healthier not to make that way but ramen isn't healthy food.
Other izakaya foods tasted good but they are $1~$2 more expensive than the same quality restaurants in California. Onigiri shouldn't cost $5. It's usually the one of the cheapest food in izakaya. It's maybe hard to make it as inexpensive as California but still too expensive.
If they could lower the price by $1 for all izakaya menu, I'm sure this place will be packed with Japanese people.
