We have been following Sushi Ken owners for more than 10 years since Sushi Ten, which the couple previous owned in Tucson. Still great Japanese food prepared by Japanese chef. Pricing is reasonable in most cases (Not sure why their Boat No. 3 is now $74 though) and arguably one of the best Japanese restaurants in Phoenix that serves good varieties of authentic Japanese food. They still have some American food just in case you are a "California-roll" type of diner.
I love wasabi octopus and other "hard to find" Japanese food that probably only exist in this restaurant within 100 mile radius. Their sashimi aren't the best as the cuts are very average. I do notice that their sashimi quality starts to head south recently, so I will only vouch for other Japanese food here and not the sashimi.
Ps. They serve all 3 major Japanese beer brands for those who cares.
