For that price, the sushi is amazing! They are also the only one that opens so late. Every other places is closed by the time they are still booming.
I used to go there all the time when I was in undergrad, they've consistently satisfied me. Don't go expecting to be fine dining, but go expecting great value for some pretty good sushi. Quick service even if there's a lineup. There's a pretty good reason why there's a lineup as well.
