I go to Inaka Sushi regularly, at least once a month (when possible).
Leo (the Owner) is a good guy and treats me very well. He is currently the chef for the sushi as well, and I believe makes once of the best Rainbow Rolls that I've had.
Inaka has your typical kitchen foods (gyoza, shrimp tempura, etc...) but I believe it is is the Sushi that stands it apart.
The decor is o.k., the staff will occasionally look like they are running around without their heads when they are busy, they are attentive and try to do the best for their customers.
I don't know how this place stays in business as the fish is fresh, Leo looks to make sure you are full, and the prices are great for the Henderson/Anthem area.
If you are looking for AYCE (All You Can Eat) Sushi, I think you should give this place a try.
