    We dined here twice during our stay at the Four Seasons resort in Westlake and each time we had an excellent experience. The service is top-notch and the quality of food is outstanding. Everything we ordered was absolutely delicious. A few of our favorites include the Wagyu Ramen, spicy edamame, and brussels sprouts. They do not have non-alcoholic beer, but the lemongrass ginger tea is delicious. Definitely recommend Onyx.

    Went there with another couple for New Year's Eve. The 4 course pre-fix menu was good with 2 or 3 choices per course. Presentation and flavors were good. Drinks were pretty expensive and may have had "new year's eve" prices. Service and staff were all friendly. We had free New Year's Eve gear on our table (hats, noisemakers, streamers) which was nice. Also included a complimentary glass of champagne. Would have been 5 stars but it was a little pricey for what you got in my opinion.
