O-Ku provides a fresh and innovative take on traditional Japanese sushi and cuisine. O-Ku’s menu is comprised of signature starters, contemporary Japanese entrees and seasonal traditional sushi that reflect the uniquely designed space. The beachside location with waterfront and rooftop dining offers traditional sashimi and specialty rolls, sourcing seafood from the finest fish markets in Tokyo and Hawaii alongside local and seasonal ingredients.
So I’m no world expert on sushi but this was the best sushi I’ve ever had. The taste was fresh, the textures were amazing, and the presentation was beautiful. It was a little spendy for what I’m used to, but the quality of the food made me feel like it was so worth it. We ordered different things from all parts of the menu and everything, including dessert was delicious. We did order some of the small plates and drinks off the happy hour menu and that helped keep the bill under control. The service was not “fast” but we were not neglected in any way. In fact it was just the opposite. We were there to celebrate a birthday and the staff went way above and beyond to make it so very, very special. They really helped the birthday person feel like a VIP. Thanks, O-ku.
I do recommend you get a reservation. Even mid-week all the tables were full.

Joseph, or “Joe,” is hands down the absolute pinnacle of waitstaff. His knowledge and passion throughout the evening was infectious. It was the best birthday dinner I’ve ever had, and it’s all thanks to him and his service. Peak dining experience.

We went for Mother’s Day lunch, had the best experience. The bento box was amazing. The sushi was amazing. Everyone working service was so kind and helpful. Can’t wait to be back!

To O-Ku at Jax Beach,
We are writing to formally address a deeply troubling incident in which a member of our group—an individual who has hosted multiple events at your establishment—was refused service by your staff. Based on the circumstances reported, this denial of service appears to have been rooted in racial discrimination.
Let us be clear: refusing service to someone because of the color of their skin is not only morally unacceptable, it is a serious violation of basic civil rights. What is equally concerning is that this incident aligns with numerous public reviews and accounts suggesting that this type of behavior may reflect a broader and ongoing pattern within your establishment.
This is not a matter that can be dismissed or handled quietly. We expect immediate action, including a thorough internal investigation, accountability for the individuals involved, and a clear outline of the steps your business will take to ensure this does not happen again.
We require a prompt and substantive response. Failure to respond appropriately will leave us no choice but to escalate this matter publicly. This includes contacting local and national media outlets, filing formal complaints with civil rights organizations, and pursuing all available avenues to ensure this issue receives the attention it warrants.
Your establishment benefits from the support of the community. That support cannot and will not continue in the face of discrimination.
We strongly advise that you treat this matter with the urgency and seriousness it demands.

Hey, I am sorry to say that I have not posted reviews prior - we’ve had exceptional experiences here. In our first experience, we had waiters coming to the table with lemons and hot towel rolls for your hands . That disappeared after a while or we actually saw it applied to some tables and not others still we always have consistently good food actually great food and we always eat downstairs inside and the food came on time. We didn’t have any issues. Well, this time let me tell you it was way different and definitely a game breaker. We arrived there tonight and the second we walked in we were hit with a wave of a horrible smell. I used to work in restaurants for 20 years so I know that smell that something is rotten. At first, I thought maybe it was the rug because the second we walked in the door I had a wave of that smell but as we moved in and continued, we were seated downstairs and we couldn’t even stay there. I knew I could not eat downstairs inside there because it smelled so awful the whole place smelled like a dirty mop. We were seated upstairs in the outdoor patio and it was better, but that fume radiated throughout the entire restaurant as we walked to the upstairs outside patio. My husband and I couldn’t understand how anyone could even eat in the inside downstairs or how the staff could even tolerate that smell. Dirty mop bar rot smell. And a $200 meal. Plus, the kitchen was totally behind so wondering if management has changed and that’s what’s going wrong. Other customers were leaving being Apologized to.
I really hate posting this because this was favorite sushi place but something’s gotta change or we will not be back.
