    Enjoyed another excellent dinner at Onyx! Especially enjoyed two of the specials offered (the miso glazed sea bass with delicious seasonal vegetables and the soft-shell crab salad). Other favorite dishes include the grilled kama tacos, the wagyu ramen, the ora king salmon crudo, the gyoza and the perfectly prepared nigiri. While many of the items are delicious, it is always a special dining experience to enjoy the specials (if offered) and the Omakase menu.

    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 :)
