I've eaten at Tokyo House quite a few times over the past few years, and I do I tell myself that I won't go back, but it's the only Japanese restaurant nearby, so eventually I end up giving it a try again.
The tempura is very heavy and greasy, the sushi is sometimes alright and other times very disappointing. The fish definatly could be fresher, avocado is sometimes used that isn't ripe yet, ect.
The service is always good, very friendly people and the atmosphere is nice. I wish the food was more constant, because I'd like nothing better than a good Japanese place in Marysville or Arlington.
There is always a lot of people eating there, so maybe I'm just too picky, but for me it's worth the drive to Rikki Rikki or Izumi in Kirkland or Sushi Hana in Lynnwood.
