Basically, if you've ever walked through the Annex at dinner time, you've probably seen a line up outside of this place. Why? Because it's cheap. Really cheap. And the portions are big.
The quality of the food is good, but not amazing. I've had better tasting sushi elsewhere, but I've also paid twice as much (if not more) for it.
Regardless, the food here is tasty. I'm a fan of all of the rolls (especially dynamite roll and mango roll), and the chicken katsu u-don (fried chicken with thick noodle soup) is really good too. The seafood salad is also a hidden gem. So is the salmon pizza and grilled squid. The more I think about it, there are a lot of great items here, but I'll stop there.
These guys do takeout too, so if you're craving cheap sushi but don't feel like waiting for a table, you may want to consider that option too.
