Ninja is close to my work and I frequently go there for lunch. The place is small (only seating for about 20) so finding a seat can be a problem, but the food makes it worth going and the tables do turn over fairly quick.
They have a wide selection of sushi and bento boxes. The sushi is super fresh and it comes out really quick which is nice. The place does a lot of take-out so if you see a line there's a good chance they the majority of them will be getting it to go.
