Extremely overpriced. The price and the quality do not match. When you’re paying that amount of money for sushi it better be the best and it’s very average at most.

My family and I had a wonderful experience at Onyx. The food quality was exceptional from the nigiri, sashimi, ramen, hand rolls and dessert! The server, Christian, was friendly, attentive, and really made us feel welcomed. I definitely look forward to coming back :)

Great Place. Great service. Good meeting place. A few different places to enjoy a cocktail after dinner at the Four Seasons. Or enjoy the Art Gallery above the Spa area.
