What our guests are saying
My wife and I visited Seiko last week and we were very satisfied with the food. I ordered White Tuna carpaccio for appetizer and I got to say that's my most favorite dish from Seiko. Thinly sliced tuna with a tangy sauce they put in the plate really brings out the flavor. My wife ordered Kamikaze roll and couple other ones. They're all very good, crunchy and filling. Definitely coming back for more.

Place is BYOB. Have dined in and ordered take out before and they are both amazing! 10/10 taste. Highly recommend the hot stone bibimbap! Would go again to try out other items.

We have been trying every sushi place by us since we moved. This has so far been my favorite. The food is incredibly fresh and tasty! I have no complaints at all. The staff is absolutely amazing. When I say staff I mean the single person holding it down. Absolutely crushing it. Incredibly nice and attentive despite being overwhelmed! Stop by and show some love absolutely won't disappoint.
