I like the Mesa and Tempe locations better, but this place suffices if I'm in Old Town Scottsdale and need a sushi fixin'. Service can be slow at times, but it's not all that bad. It's hard to get a table though, especially on weekends - even if you call ahead of time.
As for the sushi itself, like I've said with the other locations... it's not fantastic, but it's not horrible either. If that's not your thing, go with the teppanyaki, especially during happy hour (again, if you can get a table).
