Such a great place! Fresh quality sushi and poke bowls by the pound. I had both and they were so good! I highly recommend this place!

Genius!!! Such a great sushi venue. No waiting, you decide which sushi and how much. The poke bowl bar is full of fresh choices. The sushi rolls are huge! Three bites per piece at least. Hot and cold rolls and ramen menu too. You just can’t beat this for awesome food.

Tried the boba, tried the ramen, tried a good mix of sushi. Amazing all of it. I’d argue these guys have better Brown Sugar Boba than Tiger Sugar themselves. The regular Tonkotsu was killer, but the black garlic was just next level.

I am extremely impressed! This place undoubtedly serves the best teriyaki in town! The ramen was incredibly delicious and full of flavor. The sushi was fantastic and truly authentic to Japanese cuisine. I'm so glad a gem like this has opened up in the area, it's a must-visit! The staff were wonderful! attentive, friendly, and engaging. I can't wait to return!"

Very delicious! I definitely recommend going here and checking this place out! Id say Fuki has a run for their money! The staff here was very friendly and informative and the atmosphere is inviting and warm. I also recommend the boba tea as well as the sushi here. it's a self serve style for the sushi and is presented beautifully! if you're nearby I definitely recommend. Such a lovely place!

Love this place!! Really good food and variety. I love the fact you can just pick your sushi roll and have a seat. The rolls are huge and filling. The owners and staff are so very helpful and they make you feel comfortable. Very nice place and budget friendly.
