I lived in Japan for 17 years (my wife is Japanese), and we have been on the prowl for a good sushi restaurant in Chandler....not just a place that give you some specialty rolls (which are mostly unheard of in Japan). Mikado Sushi comes the closest we can find to "authentic" Japanese sushi, which is hard to find being that we are in the middle of a desert.
The quality was very good. Service was excellent. Very reasonable prices. They even have a beer from Gunma prefecture which added to the experience. I would say you will never get close to the quality and taste of Japanese food in Arizona, but this venue will be as close as you can get.
It definitely gets crowded on a Friday night between 6 and 7. Avoid those times. But after 7, it thins out very quickly.
