Brianna and I did a pick up/take out from O-KU. The food was really good. Brianna ordered the Poke Hawaiian Tuna and was disappointed the dish did not come with Rice. However the quality of the food was excellent.
I tried a Tokyo Chicken Donburi. It was good but nothing like a sushi dish. The chicken was cooked.
We also ordered 4 pieces of Maguro and the quality of the sushi was outstanding.
The place was in a cute location and had some awesome heaters outside. I would say there was 4-5 tables for outdoor eating.
I would really like to try this place again for Sushi!
