Decent Japanese restaurant. My group ordered a big sushi boat and a bunch of other items. I chose the sukiyaki don. The fish is pretty good and the sushi was a favourite among the group. The rice bowl could've been better. Staff weren't that attentive. We tried getting the attention of two waitresses who were chatting with each other and the person who helped us in the end was a waitress taking an order for another table

All the sashimi are so fresh and yummy !!!! Friendly staffs, very good Japanese family owned business with fair price. Best if you sit at the sushi bar and order the fresh / live items of the day. Sometimes it will get pricy since it's market price, but you can always tell them if you have a budget or your preference of the fish and they will arrange for you. You can also order 1 by 1 unlike some places that only allow you to order omakase at sushi bar.

Parents of a friend from awhile ago owns this place. Was told about their Hikaru Bento and had to try it. Definitely wish I had not nigiri or sashimi instead of the comes fish. Maybe they can substitute if you ask. Not sure if it's the same every time either. Overall though it was really good. I never questioned the pricing while I was eating.
