- OKOlha KotovaMar 7, 20265.0Amazing Japanese restaurant. The fish is incredibly fresh, the sushi is delicious, and the discounts are great. Highly recommended! The staff is also very polite and attentive.
- GLGrace LimJan 9, 20265.0Cristian and Valeria were very welcoming and made a pleasant atmosphere. They were courteous and explained details about the food. Chicken Karuga was well prepared and savory with a nice complement sauce. Thank you
- AHAngela HoDec 7, 20252.0We haven't been out on date night since COVID started (sad, I know), so we were very excited to come to Onyx, especially since the restaurant is located inside the Four Seasons. The hotel itself was beautifully decorated for Christmas. The restaurant is classy, but dress code is casual. The service was excellent, but the food was so disappointing! The meal started out good enough with the tuna tartare rice cakes and scallop/lobster dumplings, but quickly went downhill. One thing to note: I did not find any garlic chili crunch in the dumplings, but the shellfish broth was delicious (but maybe provide a spoon so patrons can actually drink the broth without looking like barbarians). We ordered the following maki: toro, hamachi, and spicy tuna. Toro was hands-down the best. The other two were mediocre. Next came the fried rice and crispy Brussels sprouts. The rice was mushy and overly salty. The Brussels sprouts were over drenched in tonkatsu sauce. Highly do not recommend! Last item that I also do not recommend is their A5 Wagyu specialty roll. The roll simply tasted like sauce and left a strange, unpleasant flavor in our mouths. Not only was date night an epic fail, we won't be back. If you know your food and truly looking for good sushi, this restaurant is not it!!
