Great ambiance, loved the roof top, relaxing, nice view. We were underwhelmed by the food, the rock shrimp lacked flavor and tasted almost burnt, the fuego roll was good, nothing to write home about, the sake nigiri however was great, and the best thing was the sugar and spice cocktail. The service however was extremely lacking, definitely put a damper on the night.

O-Ku really raised the bar for sushi in Jax Beach. They offer a wide variety of fish you don’t find at most sushi spots and they infuse subtle notes of flavor without overpowering the deliciousness of the fish itself. If you visit O-Ku you’re going to be impressed. The upper level also has a nice ocean view.
