Have eaten here many times in the past and am consistently impressed by the quality each time. I've occasionally had an off night even at upscale sushi joints around town, and although some visits have tasted better than others at Sushi Ninja, I've never been let down.
Love the Kim chi in the chicken bento box, the California roll is one of the best I've had (I know, not super authentic sushi but it's terrific). Also recommend the rainbow roll and anything tempura there is very good. It's nothing fancy inside, but for a quick bite in, or better yet to go you can't miss. Will try the udon in the future but I'm not sure if I'd know if it's good or not?
