I was really looking forward to trying O-Ku in Union Market, but the experience fell short. The sushi rice was extremely hard and crunchy, almost like it had been sitting in the refrigerator overnight, which completely threw off the texture and flavor of the rolls. For a place with O-Ku’s reputation and price point, I expected much fresher, properly prepared rice. Hoping this was just an off night, but it definitely impacted the overall meal.

I went here late on a Tuesday when i was craving sushi and it did not disappoint. I got the yellowtail and sashimi and another roll that was like a crunchy tempura. I can’t remember the name I think it has fried salmon anywho it was DELICIOUS! It may have been the firecracker roll. Theyre drinks are pretty good too. Would recommend coming later in the evening when parking is better to grab

We loved this place!!!! Came here on a whim and got seated at the bar right away at 7pm on a Wednesday. Our server, Zach, was so good to let us know that we had 3 minutes to order from the HH menu.
Our four rolls all tasted really delicious, though we’d probably save the harvest roll for sweet green 😅 if you’re a sushi connoisseur, we’d say the rice was a tad undercooked, but we still loved all the flavors.
Non-alcoholic drinks were definitely on the sweet side, but again, flavors were fantastic.
Get the sata andagi for dessert. Pillowy-soft and melt in your mouth and the dipping sauce is amazing! 100/10

I usually do not write reviews, especially bad ones, but this is worth noting. I came here for to celebrate my first wedding anniversary and was so excited to try their sushi but was underwhelmed in many ways. I think that night there were some delays in the kitchen which was fine, but the food sucked, and we had to wait a while. Fish quality was so bad that both my husband and I had to spit out some parts of the fish because it was inedible. We paid $85 for basic nigiri with bad fish quality. I could get the same meal with fresh delicious fish for $35 in NYC. Absolute scam and rip off for what you get and the quality was awful. Not worth it at all and so devastated that we wasted such a special dinner celebrating our first year anniversary here. I do not recommend. Save your money and go somewhere else.

O-Ku was overall great! The seared tuna app and scallop temaki hand roll were amazing. My husband ordered the yakisoba noodles which I think was the star of the evening! The pork belly in the noodles was truly so absolutely delicious.
The two rolls were good (Mt Fuji and I can’t remember the other one), but they felt underwhelming for the price point. One was essentially a California roll with a bit of seared salmon on top for $20, just felt like a mismatch. I wish I had done the chefs nigiri or more hand rolls. The only other issue was the sushi came out like 15 minutes before my husbands food so timing wise, it was a little awkward - you don’t want to be eating while someone is waiting or be completely finished before the other person gets the food. It’s not a huge deal, I just waited, but most places are able to time when to send all the food out at once.
