Sushi here is to-go, and although they do offer seating you will still be eating out of plastic.
That said, the sushi is tasty and fresh! I can't speak for the sashimi or anything, but a basic boring sushi eater like myself (cucumber avacado roll and miso soup, please!) can get a decent lunch here for $7 or less.
It's affordable, quick and convenient. Hits the spot for lunch every time!
