Sushi Ken is a hit or miss. I've been here on several occasions in the past couple of years and I've ordered great food, good food, mediocre food, and bad food. The service has varied from decent to bad, and yes, if you ask to split the check they automatically add a couple extra bucks to your bill without telling you. A little deceiving, if you ask me, but the reason I keep going back is because their prices are great and (some of) thier food is pretty good for a Japanese restaurant in Arizona. In my opinion, it's worth trying out if you don't walk in with high expectations for food and service.
