    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.
