What our guests are saying
We had a fantastic meal here! The food was delicious with good portions, good prices, and really knowledgeable, friendly staff. We had a chef's choice sashimi and the katsu beef with an order of the grilled beef. All winners! We certainly want to come back to try the prix fixe dinner.

This restaurant was such a treat! Their food is authentic and delicious. On top of that, we met the co-owner and owner, who were very friendly and added more to our experience. If anyone is craving authentic Japanese food, you must check this place out!

This place is delicious! An authentic Japanese menu with a great range of options. I loved the Tendon bowl and the potato croquettes. I would recommend this spot for anyone looking to explore more Japanese cuisine beyond sushi.
