One of my favorite sushi places in Seattle. It's a bit of a hole in the wall in Everett, and not the greatest service, but if it's great sushi you're after (and lots of sushi) then this is the place.
They have an all-you-can-eat option for like $28. Comes with calamari and mussels, and then order anything you want.
My favorites are the El Presidente Hand Roll and the Scallop Hand Rolls. Gotta get the hand rolls - SO GOOD. They make it right in front of you and hand it to you over the counter - can't get more fresh than that! They're normally about $6 each, so eat 3 of those plus the mussels and calamari and you've made your money back. I ate about 6 or 7 rolls, several sushi and nagiri (sp?) so it was definitely worth it.
I highly recommend this place - again not a ritzy place, but great for a fun lunch or dinner.
