Why don't you visit the Sushiland in the Bella Bottega area of Redmond? I used to live in Redmond and went there about 5x a week. Its a conveyor belt, with sushi starting at $1 per plate.
There is also a Sushiland in Bellevue, but it sucks. Don't go there. Its always full of high school brats who demand rap music on the speakers.
There a Sushiland at Southcenter that I haven't been to. The Sushiland in Lower Queen Anne is just okay. Redmond is the best, by far.
