Food was ok however no value for the price
The chairs were filthy black food grease or black body oils on the fabric yuk
The floors are wood and need restoration scratched dirty and more
This should not be the level of restaurant to be associated to the four seasons name

Fantastic food, service and cocktails. Clean and neat throughout. All the employees were a joy to talk with, with great personalities. All come by from the manager down to make sure you are happy. The food has incredible taste and is presented very well. The atmosphere and decor is very warm and classy.

I took my two teenage sons here for a birthday celebration. Cory gave us excellent service which was very appreciated. At one point a manager showed up to make sure that everything was going well. This is a huge improvement from the last time we dined at the Four Seasons. Last time felt more like a coffee shop then fine dining but they obviously have stepped up their game!

Food was very fresh and tasted great. Pricing was higher than expected. Sushi is pretty costly in general so I did expect a hefty tab. We got two appetizers, three specialty sushi rolls, one California hand roll, one tuna hand roll, one egg handroll and a side of garlic noodles. Total was about $200 Plus tip. They were kind enough to bring a special dessert for my son’s birthday. We did not have any drinks, alcohol or other desserts.

Although pricier than anticipated it was a really fun evening and I’m glad we chose Onyx for our celebration.

Really slow service. The slowest we’ve had in a long time. Not what we expected from a restaurant at the Four Seasons

Good but there is better sushi and ambience for cheaper options. Service was good, not memorable.

I was seated at the sushi bar and enjoyed one of the best meal ever. The chef was very skilled and entertaining, the fish was delicious and fresh, the staff was very attentive and pleasant. The venue is easy to locate and parking is convenient and free. The hotel and restaurant decor needs a refresh, but it did not bother me.

Our server was very patient in explaining the Travel zoo deal, what it included. He offered great suggestions on drinks etc.

Onyx is always amazing! We try to have dinner there at least once a month. The food and service are wonderful. We look forward to our next visit.

We have always enjoyed our dining at Onyx. Our waiter was wonderful! He recommended a fabulous red wine. The smaller portions leave us satisfied without feeling stuffed! Can’t wait to go back!

We have been to Onyx many times. On this occasion we had invited our friends over to have a nice dinner. Service was unusually poor. They forgot to bring our appetizers, main dishes were all mixed up. Kids had to wait much longer than they had to despite us asking their food first. Very disorganized last night l. I hope it is a one off as we love the place and the food otherwise.

This was our second time to Onyx and the second visit was just as perfect. Amber and Emma greeted us when we arrived and welcomed us back along with our guests (my family) - a very nice surprise to be remembered.

Once seated, Jesus welcomed us back and took our drink order, checking in with us on how the drinks and appetizers were once they arrived. Throughout the meal his service was friendly and personable which made for an enjoyable environment, even using our names.

The food was exquisite - especially the Volcano Roll, Black Cod and delicious sides - the presentation was beautiful. They even warned us of mushrooms in the noodle dish as they set it down, knowing my husband wasn't a mushroom eater. They remembered that fact from our previous visit! We will definitely return to Onyx for another incredible meal. Thank you to all the staff who made our dinner so wonderful and memorable.
