    We were disappointed. The wagyu was fatty and tough and the seabass was crunchy and dry. The manager was very attentive though and took off our bill but our expectations on food quality were not met at the level we expected.

    Enjoyed an exceptional dinner at Onyx tonight! Every item on the new Omakase menu was delicious, including the perfectly prepared Nigiri sushi, sashimi, grilled scallop, toro handroll and the miso butter striped bass! Already looking forward to dining at Onyx again soon as our meal was sooooooo good!

    Food was amazing. Service was great! Server spoke about each dish and explained how it was prepared. Also server did a Sake pairing with the dish. First time here and fell in love with it.

    Our 10 yr anniversary. Sat outside the heater was nice to keep us warm. The food and service was good. Thought portion was small for the price

    Went here about 5 years ago and had a good experience. They completely changed their menu since then, which equated to a big negative and kicking myself for taking my party of 4 there. If you are looking to spend an extravagant amount of $ and still be hungry after you leave, this is the place. Their end-game is tapas style food items that are very expensive for what little you get... thinly sliced nothings. They are clearly capitalizing on being a restaurant in the Four Seasons by completely overpricing everything on their joke of a menu. Giving very little for a boatload of cash. Will never go back. Kick Onyx to the curb. My advice is to drive a little further and go to an authentic sushi/sashimi restaurant, Sugarfish in Calabasas.

    Seating is terrible. If you don’t get one of three booths it’s a terrible seating experience
