We had dinner here on Black Friday. The restaurant is much too dark inside, making it very difficult to read the menu (and making me wonder what they're trying to hide). It was also much too noisy for us to have a relaxing time. The biggest disappointment tho is that they don't serve hot sake....whoever heard of a Japanese restaurant... More

First time visiting for my fiancées birthday. We sat at the bar and ordered some quick sushi before catching a movie. Kaeli was our bartender and she was warm, friendly, and knowledgeable. Would return just to see her. I recommend the 463 roll, the dapper snapper, and harvest. Also happy hour M,W,F 5-7 is great. Six sushi rolls and three... More

Four of us had dinner reservations on Black Friday and were seated promptly. I had read reviews of how dark it is inside and yes, those reviews were right ~ we just used our phone to shine light on the menu otherwise you don't really need the light. The ambience definitely made for a nice, relaxing evening. To our surprise,... More

Had dinner there on Friday night. Busy and loud so hard to have a conversation. The sushi was good but the portions of nigiri were small and the scallop roll was kind of clumsy to eat with the baked scallop on top of the roll which didn't stay put and therefore kinda defeated the purpose of eating it in one...

10/10 recommend visiting Oku Monday, Wednesday, Friday during happy hour. Half off sushi and discounted drinks. Best sushi spot I have ever been to. Ambience is great, and service is attentive

Loved the food here! The service was on point as well; everyone was extremely nice! The only thing that kept this place from getting an 'excellent' was the restaurant itself. It was extremely dark (I had to use the candle on the table to read he menu and everyone else was using their cell phones) and the acoustics were horrible.... More

It's always a gamble to try to replicate a great experience, but we had such a fine time with the omakase dinner last year that when we were planning this year's trip to Charleston it was number 2 on my list of restaurants we must get back to. It's possible that this year's experience was even a touch better than... More

Manager said too busy on happy hour days as the food won't be right. Went in at 5 no one at the sushi bar, no greetings from the 6 sushi chefs there. No interactions at all with them. They just rolled sushi in advance. The cold items; ie nigri and the warm items stone cold, soft shell crab, and unagi.... More

Popped into this place for a drink and ended up having some awesome snacks. The drinks were pretty good, staff gave us great service but the vegetable and fish spring rolls were the highlight of a good evening.
