Onyx is always amazing, and this time was no different! Their lobster spring roll is to-die-for. I absolutely love it! My sushi and my husband's fish were both superbly prepared. Great stop! Highly recommend.

I had higher expectations. There was a lot of hype about Onyx that I really expected more, Staff was great and the food was very good . However, it didn't have the "Wow" factor that I had envisioned.

The choices for sushi were amazing. Some I had never heard of before but so delicious. There was a group of us and still the service was excellent. If I lived in the area, it would be my go to sushi bar!!

The setting here is trendy and upscale, we were able to have a table outside overlooking the koi pond, it felt as though we were in a tropical setting. Service was very good, as was the food. Great shishito peppers and steak!

Specializing in fresh seafood and sushi, ONYX at Four Seasons Hotel Westlake Village offers delectable Asian fare. Backlit wall panels of semi-precious stones, such as carnelian and onyx, create a dramatic dining atmosphere. Bamboo floors, Japanese antiques and chandeliers grace the main dining room, while silk lanterns hanging over the sushi bar give an exotic feel. Watch while the freshest Japanese delicacies are being prepared, or sip a drink at the bar, where colourful aquatic creatures live in a double-sided, 2,000-gallon (7,571-litre) saltwater aquarium. A variety of sushi, sashimi and specialty hand rolls complement delectable Asian-influenced seafood creations. The menu offers many options to sample a variety of dishes, intended to be shared at the table. Also pairing well with Japanese cuisine is an extensive wine list featuring choices from California and around the world.
