    Went to Ok-U last night for the first time with my husband - I am originally from California and like to believe we have the best sushi in the US, but after dinner last night, I think Ok-U is the best sushi in the entire SOUTH… and even rivals the west coast. We had the miso soup, hamachi and salmon carpaccio/ceviche (thank you to Jose for!) Otoro shots (AMAZING) a torched black cod nigiri, tuna tuna roll, reedy river, GVL goddess, and I can’t believe I’m saying this but the rainbow roll (⭐️⭐️⭐️⭐️⭐️). Literally this roll is the best roll I’ve ever had - it has a truffle sweet soy sauce on there that will blow your mind. I am Also GF and DF and did not have to compromise in any way during this experience. Our server, Noah, was so kind, helpful, informative, knowledgeable, and so professional. Also big thanks to David! You were awesome and great to talk to, Jose on the sushi, and the manager who checked in on us. Thank you all for an amazing night I can’t wait to come back!

    I want to begin by recognizing and apologizing to our server Noah. We could tell you were honestly ashamed by the kitchen’s failure to deliver an omakase experience for two and appreciate your efforts to soften the blow of disappointment for something we were quite excited to try. We’ve been to Oku in Greenville a good number of times. It’s one of our favorite places for a nice meal and I’ve always told people that we’ve never had a bad experience or bad meal there, at least until now. We booked omakase for two at 5:30 pm, two weeks in advance via calling the restaurant, as the menu states there’s limited availability, so I wanted to make sure I was clear about our reservation and what we were coming in to do. It was recommended that we come early as it is a longer dinner (around 2 hours). When we arrived, this was perhaps not communicated, as when I told our server that we were there for omakase, he said he would have to ask the kitchen if they would be able to do this. I then mentioned about the steps I’d taken above, and he went and checked and said the kitchen was good to go. He warned us that the start is usually slow, but after the first couple, it picks up and is a good amount of food, so hoped we were hungry. We definitely were but were optimistic everything would be great. From 5:30pm - 7:30 PM we’d been served 4 of the 8 courses. If you do the math on that, it’s about 1 course every 30 minutes. Now imagine that you arrived hungry and you're waiting 30 minutes to eat 3-4 slices of excellently prepared fish in about 1-2 minutes. I will recognize that the first three courses were delicious, but it wasn’t anything substantial, so by the time the nigiri 2.5 hours into the dinner, I was nauseated. At this point, we were contemplating ordering something off the main menu or leaving. Our server made it back around and we asked how much longer it would be for the rest of the meal and he said the next course would be out any second. Shortly after, we received 6 raw oysters and asked for the check. In nearly 3 hours, we received 6 of the 8 courses and had watched the entire restaurant turn over at least twice, and decided we didn’t want to see it change over a third, so paid and left. One would assume that if clients book the tasting menu, that there would be a little more of an effort from the kitchen as they’re wanting to experience your top dining offering; however, it felt like we were an inconvenience. Again, this has nothing to do with our server - he was just as much along for the ride as we were, and it was clear we all wanted the experience to end. We still really like O-ku, but will be very hesitant to try the omakase from the chef again (maybe it should just be taken off the menu?).

    It was valentines day and I wanted to take my wife somewhere different locally and I remember hearing about Oku and how good they were. Well I'm here to report its as advertised. Every single dish we tasted was amazing. Full of flavor and freshness. Fish that just melts in your mouth. You have to try the Gindara chef special, its Japanese cod fish torched with a miss glaze, wholy shitake was that good. Never had cod in that way. Our waiter Noah said the cod is from Japan and different from American cod and thus can be served in such a manner. They also fly all their fish in fresh daily from Japan. Now I understand the price point. It's not a place for the faint of wallet but if you are looking for true Japanese sushi with a modern twist make sure to stop by, its worth it!

    10/10 service, food and beats all my expectations every time I go. I came for Valentine’s Day and they were super busy, I had a reservation for 10:30, walked out at 11:15 with a full stomach and great food. Reminded me of Miami with the service and the music Ann the host and Anita our server were super awesome and quick. Very sweet and on the point!
