What Diners are Saying

It was excellent. The proteins were lean and non greasy, and the presentation, service, and atmosphere were great. The place looks dead when you look at it from the Castro Valley Blvd side. Most patrons park in the back of the premises. I will surely return.

I hesitate to really share about this place because it is such a gem. It’s a great little unassuming neighborhood place. I feel like it is my treasure. It is always pristine and the food consistently really good. I get the bento box with salmon teriyaki. My kids key the nigiri and are always eat every bit . . . Even my daughter who is super particular

This place is pretty tasty! We got dinners and some sushi and the portions were great. The rolls we got were actually pretty dang big which was really nice. Definitely will be ordering from here again since we live close by. Only downside is the parking in back is tiny but there’s still plenty of places to park on the street behind the restaurant.

The menu is extensive and very interesting. They have a huge range of appetizers and a very creative range of rolls. I had the tako-yaki (octopus balls), ebi nigiri, hotategai nigiri, and the habane roll (habanero-spiced!). All were excellent. Very friendly service too.
