The sushi here is unbelievably cheap and quick. $4 will get you 8 pieces of sushi in a variety of forms (including dynamite rolls, sweet potato rolls, and California rolls). You can upgrade with some gyoza or help yourself to some complimentary miso soup.
While I can't say the food here is particularly delicious, it does the job when you're on a budget.
This place is always busy during lunch hours. The wait will only be a few minutes though since everything is pre-made and packed in easy-to-take-out plastic ware.
