Across from Claskamas mall some where on OLD NAVY side there is a place call Sushi Land/ Sushi World, once you go in they let you sit in the bar that had the belt running around the food bar. There will be plenty of sushi plates rolling around on the belt for you to pick... price range from $1.50-$3.00 per plate. Very decent price.
For those whom like big Sushi eater and all you can eat sushi then go to Pioneer Square, there is a restaurant in it call Todai restaurant $27 for dinner and $13 lunch per person, they have all kind of sushi including fish only that is unlimmit, plus any special rolls that you want you can get it from them too. They also have lobster (giant shrimp for me) for dinner.
There is a vietnamse restaurant around 68th and Sandy call Yen Ha restaurant. They do have a lot of special food that you must try in your life time. Wild pig BBQ, Fresh Duck Blood (they make it like pizza but taste a lot better), Python meat, Raw fish soup, goose meat and many more. If you really want the food name so you can order contact me :-) I used to be waiter at that restaurant 12 years ago :-)
