you're looking for a classy night out, whether it's a romantic date or an evening with a group of gentlemen, girls night out, Onyx is the perfect spot. Elegant, stylish, and undeniably high-end, it offers a refined atmosphere and exceptional service! Be sure to try their signature dish (I'll upload a photo!), and don't miss out on one of their crafted cocktails and a decadent dessert to complete the full experience. Pro tip: Take a post-meal stroll through the stunning Four Seasons gardens.. always a beautiful way to end the evening. And if you're visiting during the holiday season, the hotel transforms into a winter wonderland. Simply magical. Highly recommended! read more

We 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!! read more

Price point that doesn't match for not so good tasting sushi. If you know good sushi you know this is really just soso. The rice quality was not good. Staff were nice. Ambiance nice. read more

Onxy is located inside the Four Seasons Hotel in Westlake. I made a reservation for dinner but walk-ins are welcome. Upon actually walking into the establishment, I wasn't greeted at all by the Staff or the Sushi Chef despite them all being well aware of my arrival since the restaurant is actually very small and we all made eye contact. It felt strange at first, but after my party and I was seated, service ended up being really good for the rest of the evening. There wasn't much of a sushi / sashimi selection but overall, everything tasted fresh. My favorite was the miso soup served in a tea pot and I was happy with everything that was ordered, however the bf gave Onyx just a 5/10 rating, even though I am usually the picky one. I've stayed at various FS hotels and it is nice to find something that is not the usual Steak or Pasta. Prices are reasonable, but I cannot recall whether they offer Omakase. The total for two for food and a bottle of Sake came out to about $400. I am planning to book a staycation at the hotel some time this month so I am looking forward to coming back again. read more

What a wonderful experience. Our server Ricardo made us feel so welcomed and comfortable. He guided us through the menu which encouraged us to order things we usually would not have. The rest of the staff for so personable, especially Anna. The manager Alexia was extra attentive and we even got to meet the executive Chef. We wanted to stay forever and eat the whole menu. read more

Disappointed with tonight's dinner. The sushi/sashimi were slightly fishy again. The rice was just ok, I'm not sure it was seasoned. I might just stick with cooked food moving forward. One star deducted. Service was sub-par. The waiter got my order wrong, and also forgot a few items even though he appeared to be "writing it down". The busier was more attentive than the server, and even asked if I wanted another drink when it had clearly been empty for some time. Another star deducted. Ambiance is great as always. I always love watching the live tank located behind the sushi chefs. Will be awhile before I give this place another shot. Hopefully their consistency will improve. read more

Some of the Malibu locals recommended this place to us to check out, and it was definitely worth it! Hidden in a hotel, this Japanese restaurant is very elegant looking but has a casual family and welcoming feel. We ordered the omakase for the evening, of which they give you two choice types; one with more fish and the other with more exotic sushi types. We also ordered the sake pairing to go with the dish. The prices were perfect for normal omakase. With each course, came more and more mouth watering sushi, each better than the next. They even brought out fresh wasabi for us to use. The service was incredible and attentive, they even walked us thru each sake course which was very informative. At the end of the courses was the matcha strawberry chiffon desert which a perfect end to the evening. Highly recommend this place for some of the best sushi we've had in a long time! read more

My family has another great experience at ONYX. It's everyone's first choice for a dinner celebration. The service is incredible. Our server took on the challenge to just surprise us. We weren't let down. He made the effort to find a sake that matched my taste when I had no idea what I'd like. The food presentation was beautiful and artistic. There was nothing served that we didn't enjoy. 5/5, we'll return read more

Food and service are top tier. Our server Christian was not only super professional and kind, but he helped to guide us on what items to try, and made some recommendations that my brother and I loved. We were torn between two different sakes so he let us sample each of them to make sure we made the right decision. He constantly kept tabs on us and made us feel like valued guests. read more

Great food, great service. Dined here for my dad & brothers birthday celebration. The fish is so tasty and the quality is top notch. Better tasting fish than Nobu in my opinion! We practically tried everything on the menu to share but here are my top favs that I will be back for: - Negi Toro handrolls (if you are a tuna lover, don't sleep on these!) - Sake (Nigiri and Sashimi) melts in your mouth! - Kobe striploin nigiri - Wagyu striploin (hot plate entree) SO good! Our server Ocean was so lovely. Made our dinner so special! Can't wait to be back. Only suggestion is to add some crispy rice to the menu :) read more

Over priced for not so good sushi.Had to wait for 1/2 hr to be seated with a reservation.

Not your typical sushi restaurant so don't expect to go in and enjoy a dragon roll and one of them fancy rolls. Your options are limited to Nigiri, hand rolls, sashimi or apps. The price is high for the amount you get but you kinda expect the highway robbery when you eat dinner at Four Seasons but daymmmm you can't expect me to pay $8-$10 for one piece of Nigiri!! They usually come as a pair! Hot plate scallops sounded good but when they said the $17 hot dish app only came with 1 cooked scallop I said excuse me thinking I misheard him! No thank you.. don't be disappointed. All basic, nothing like OMG to rave about to be spending all that $$$$. Service wasn't even good to make up for the cost. Just No! read more

They really need to update their website. The only reason we came here was because their website offered more than just fish. We had one person with us who had a shellfish allergy so we definitely needed the other options. Overpriced. Our bill was 900 and we couldn't even all sit together. read more

Once again, Onyx shows it really is the top restaurant in Westlake Village. All dishes were tip top - nigiri, sea bass, and the sake flight was outstanding. Sealed with an amazing Japanese rendition of a matcha honeycomb dessert. THE place for miles! read more

Ate here with my friends, the chashu nigiri is my favorite thing on the menu I had the Lychee martini which I would recommend if you prefer sweet cocktails, and lastly the matcha eclair for dessert one of my friends had the cheesecake which I liked better but the eclair was still good Service was great the chef greeted us and checked if everything was good. Our bill came to almost $700 so expect to spend a little money. read more

The service and ambience are good. The food however left a lot to be desired especially for the price. The miso soup was bland and fatty, the beef nigiri tasted stale with none of the savory taste usually associated with it. The shrimp nigiri has a bad chemical taste. The sashimi was pretty good but the portions were small. read more

Oh my goodness! I'll think about last nights meal forever!!!! But seriously. Everything was super good! We each got a few hand rolls, the skewers and the chocolate roll dessert and the cheesecake dessert and... WOW. Both were incredible! read more

A lovely celebration dinner at the 4 Season and the recently read-opened Onyx Japanese kitchen - from start to finish a great dining experience including our aptly named sushi server (Ocean, yes that's her name) who kept the food and drinks coming throughout the evening. Our party of 5 tried most of the menu and found most, if not all to be delish - the only disappointment was the "fish and chips"- it's missed the spot as part of the fish and chips experience is the wonderful "crunchy batter" on the fish that was missing in this interpretation. We enjoyed (very much) the Rice Chicharron; a super fresh big eye tuna, green onions, watermelon radish, avocado, osetra caviar onto of a large rice cracker. The fish was tasty and paired so very well with the cracker underneath. We enjoyed our outside seat - it allowed our party to spread out and enjoy the April evening. The waterfall out back along with the trees transformed us from Westlake to vacation elsewhere! A great spot for a sushi celebration anytime of the year! read more

Definitely recommend this place. It is located within the Four Season's in Westlake. The parking is easy and the grounds are beautiful. We were seated promptly and the staff was all very attentive and knowledgeable about the food and the ingredients. Every dish was beautifully presented. The food came out in a timely manner and was delicious. The fish was very fresh and flavorful. No complaints, will definitely visit again. read more

It saddens me to write a negative review for Onyx. My husband and I have dined here many times and it used to be our go-to date night spot. Between the food, the service and the ambience, we loved coming here. I also want to mention that they did a wonderful job during the pandemic and were compliant with all the safety protocols, while also providing a great dining experience. They had to close down for about a year, due to a fire, I believe. They opened back up a few months ago and we were thrilled to return. However, it was immediately clear that the restaurant menu was not the same. Someone in management made the very unfortunate decision to revamp the menu entirely and remove their best items. It also appears that they have a new head sushi chef. Our favorite rolls are gone (hayabusa roll, toro taku roll), and have been replaced by underwhelming, mediocre rolls that lack flavor. The nigiri used to be outstanding, but the quality of the fish has gone way down. They now have an abundance of hot appetizers, which might apeal to some people. However, I couldn't care less about hot appetizers at a sushi restaurant. I want the focus to be on the nigiri, sashimi and rolls. When we spoke to one of the sushi chefs (Scott) about the change in the menu, he was kind enough to bring out a custom roll that he made, which was absolutely delicious. No joke- management needs to consult with Scott on how to improve the menu because he understands what the customers want. I will say that the service is still excellent. The hosts are very professional, the waiters are so kind and the busboys are always hustling. The drink list is great and they offer a lovely selection of wine and cocktails. However, unless the menu vastly improves, my husband and I will not be returning. The high prices are insulting, quite frankly, given the quality of the sushi. My message to Onyx is- do better. read more

This was such a mixed bag of delightful and disgusting that I'm not sure how many stars to give. I am going to split the difference and say three stars, but this is how it breaks down: Our server Ocean was lovely, very attentive, very kind, gave all around good service. Her recommendations for starters were all delicious. The staff were attentive and friendly, accommodating our elderly parents needs with kindness and discretion. The decor is modern and feels luxe. Sounds great, right? The 'regular' sushi was good, the fish was fresh and well cut. But there were some random items on the menu that sounded good in theory but were absolutely mind bogglingly bad. The "risotto" was supposedly sushi rice, but was just flavorless plain short grain rice, drowned in an insipid broth with minuscule bits of snow crab and seaweed. It was soupy, but served on a flat plate. I suppose it was meant to look like a risotto, but it was nearly impossible to eat with chopsticks or even a fork. I can't imagine any actual Asian person created this dish, because most Asian cultures put rice in a bowl in order to eat it. There was lobster, but it was overcooked and tough. The chef's choice nigiri was okay, but one expects more than just the usual types of fish, no? Something a little more interesting than tamago, ebi, and unagi? I love unagi, so much that I ordered three pieces separately. Chef's choice implies something special. This was not special, though $6 more expensive than if I'd just ordered 6 pieces of nigiri separately. All in all a mixed bag, some delicious bits and some not so delicious, adding up to a solid Meh. read more

What's not to love about the renovated Onyx at the FourSeasons in Westlake Village? Definitely 4.5 stars!! It's beautiful, intimate and the service is spectacular!! Jesus was my waiter and he knows how to treat customers!! I usually sit at the bar and Keith is one of my favorite sushi chefs but I opted for a table last night. The sushi bar is now on the opposite side of the restaurant and there is a beautiful fish tank behind it. I ordered the truffle edamame which wasn't very truffle-y for $9. I also had hamachi crudo was was EXCELLENT!! It was perfectly tender and moist! I had the manga roll without rice and it was an interesting flavor profile with 3 types of fish. Delicious and $23 but that's too he expected at this fine 4 Seasons restaurant! The new manager is also lovely!! Check it out next time you are visiting!! read more

This review is not for the ambiance which is really nice. It's for the bad service we received with a party of 14 and almost everything we ordered came wrong. And it's specially for the food that gave most of us stomach problem and three of us including a child got food poisoning. After contacting the management and several back and forth they did nothing thank felt sorry. Not recommended at all read more

I feel I'm rounding up or maybe even donating a star here. Bottom line is that the service and food did not match the price or the expectations. I was really hoping I had found a slightly over-priced-but-super-high-quality sushi bar I could call home. But it was missing a few things. The server was cool... and his back-up guy (busser?) was cool and the two girls doing the seating were cool. But the fish was a little mediocre and the rolls uninspired. If the food is gonna be average, you have to step it up everywhere else... and they don't. Made ressies (on Open Table) for the outdoor seating and it was a problem (that got resolved quickly) even tho there was only one other group out there. It would have been nice to know that a wedding taking place on a nearby lawn was going to really hamper conversation at the table, the cold sake was not really cold, everything seemed like it was going about 25% slower than it should have been going. (We didn't bag on them... like I said, the server was nice... they did mention that a few people called in sick. Could be.) I mean... this is a restaurant at a FOUR SEASONS! Didn't that used to mean something? I was expecting something like just-below-one-Michelin-Star... or a Nobu vibe... maybe Asanebo? This was more like a Marmalade Cafe vibe. BUT... we are recovering from a pandemic, someone else paid the bill, I might have caught them on an off evening. But they had the freshly grated real wasabi on everyone's dishes and they didn't even mention it... nice touch. read more

Sad to announce this was very below four seasons expectations. Fish was fishy and warm, steak was chewy, and Brussels sprouts were burnt and cold. I think the four seasons should consider either an Italian or Mexican cuisine restaurant. read more

It's not like it used to be .... It's smaller and the product is mediocre . Too bad as I was really looking forward to it- I went there years ago and ate there quite frequently. The food was just thrown together and bland - no flavor. Service was not great as they only filled up my glass once with water. I would suggest passing this up for others in the community that I think is better. read more

This stylish restaurant in the Four Season serves a moderate selection of sushi, plus an assortment of hot dishes. The hamachi ponzu was fine, but not as good as other versions I've had where the sauce is less vinegary. The dynamite roll was a nice combination of crunchy and chewy textures and sweet and spicy flavors. The best item we had was actually a garlic chicken noodle side dish that was plenty for two people to share as an entree. There is small but well-chosen selection of wines, and an extensive selection of sakes, listed by type. If you are into whiskey, try the Coffey still blend. Service was outstanding. read more
