Cubé - Japanese sushi restaurant in City of London, Westminster

Incredible sushi and omakase lunch service. Best sushi in Mayfair.

Forget the bad reviews, this place is unreal

In London, you have to pay extra for top-level fresh sushi compared to Asia… but as someone who craves sushi often, what can I do? Cube isn’t cheap, but it’s worth every penny for the quality you get.

Booked months in advance for the Omakase only to be told it'll be served on a platter for £150.

Food was very bad but staff are amazing

Excellent traditional Japanese. We were nicely welcomed. All meal were excellent and freshly made in front of us. It is very pleasant to see the chef performing the preparation. He gave us as well some piece of information.m during the preparation. I highly recommend !

Nigiri was good with clear explanations, including the origin of fish by the chef at the sushi counter. But one nigiri was missing, making it just 9 pieces, not 10 as advertised on their omakase menu. So I raised that with the server to see which nigiri was missing. The server queried if I had forgotten to take photos, and I was fuming inside why customers were required to provide photo evidence of what they ate and what not. Then I replied calmly I could show her the time when the photos were taken (consistency of everything I had taken photos of). I took written notes of each nigiri as the chef explained the ingredients and took photos of the chef working and the final product. I genuinely enjoyed the exquisiteness of Japanese cuisine. The restaurant was very busy around 6pm on a Monday evening when customers rushed in all at the same time for dinner service. The chef did slice a bunch of akami, chutoro, and otoro, but none landed on my plate as the first nigiri. My first nigiri was hamachi. After the server and the chef communicated in Japanese, Chef responded in Japanese that he would do the 10th nigiri I guessed from his body language. The server said in English to me that the chef was sure there was no mistake but could do that as complimentary. When presenting the bill, they put the other two nigiri on the side as complimentary as well. The experience would have been better if they acknowledged the missing nigiri and provided it, rather than going through the argument, not apologetic, yet with "complimentary" food. After the 10th nigiri was served, I was 100% sure that was the missing piece. I did not have it on my plate as the chef said that should be the first nigiri. And when I looked through the photos of the busy kitchen, I spotted the nigiri of the same type on at least two separate platters serving the customers at the table, not at the counter. The restaurant could take this to verify with their orders around the same time at 6pm. Foodwise, all went well; the argument with the server about the missing piece on the omasake menu spoiled everything.

By far, the best sushi in London!!! The service was also really accommodating and friendly, making celebrating my boyfriend’s birthday so lovely! We both agreed that the quality and freshness of the fish was impeccable; the sea urchin served to us was just imported that day (from Iceland!). Our highlights were the octopus, fatty tuna, king crab tempura and green tea brownie! Definitely coming back again (and again) - so glad we decided to try this new find! Such a breath of fresh air to have a humble (and more traditional style) sushi dining experience, without all the unnecessary extra glitz and glam! A MUST GO!!!

Red Bream soup, otoro and hamachi are absolutely delicious. Service is epitome of Japanese hospitality

Amazing experience with daughters. Great food, people and atmosphere. Thank you

Best sushi I had in London, in a traditional non-flashy resto. Expensive, but worth it imho.

Hands down one of our favorite meals in London. The place was tiny and the staff were all welcoming and great. Now onto the meal. We did the Omakase at the counter and if you like amazing nigiri and hand rolls, this is the place for you. We ordered several additional pieces (because it was so amazing, not because we were hungry) and chef even did a couple special request pieces for us. Their sake list was brief but still great options and they helped guide us through our choices. Highly recommend and as noted tiny so make a reservation. Update: went back last night (December 12, 2024) and exact same great experience and omakase. Such amazing food and genuine service. On our permanent London rotation.

The quality of the dinner experience and the food was outstanding. The service provided was very detailed, hanging up your coats/jacket for you, changing your plates after every course and explaining the dishes throughout the experience was a cute memoir for me. Everything we ate, you can just tell the quality of the fish and beef was the best of the best. I highly recommend this restaurant to all sushi lovers and people who would like a casual date night.

Superb! Great place for lunch if you are in Mayfair.

I absolutely loved it so fun really great food my 11 year old daughter was in love best place she had ever been to 1000% do recommend. Would definitely recommend!

Perfect Japanese food. Nigiri is super yummy, Wagyu beef is just amazing. Very welcoming team. Highly recommended

Perfect birthday meal, one of the best ever! Thank you for such a special omakase experience - we will be back.

Your unpretentious local go to! Genuine Japanese place… wonderfully fresh ingredients, cheerful service… instant favorite

'Sushi omakase course' was incredible. Every piece was absolutely delicious, and it was well worth the visit. We loved the chef's creations - each nigiri was perfectly seasoned, so you don't dip them in soy sauce, you just eat them as they are, fantastic. The temaki was without doubt the best one we've had. Counter seats are highly recommend as you get served one by one by the chef.

Awesome as always. Masa and Yama are amazing chefs. Make sure to order the salads and make a reservation inside

Our server Matain, was excellent and so helpful. Delicious portion of pickled carrots at the start of the meal. We ordered one of the roll specials as well as you eat salad and a delicious soup. They were so nice to accommodate us outside and let us know when the table needed to turn since we didn’t have reservations. I really really appreciate them fitness into the schedule and we were happy to have a quick bite with such a wonderful atmosphere

Super service. Prompt. Friendly. Great food. Fantastic recommendations from manager.

Absolutely loved omakase, quality was great, rare finds in London! The portion was surprisingly big. Highly recommend.

More of local Japanese omakase restaurant atmosphere which I like, does not mean it looks low quality. The sushi is relatively a higher quality for its price considering others within the central london area. Especially they have chutoro option for those who find Otoro is too greasy, their chutoro is the spot on option for Tuna. Decent Sake options, if you never tried Japanese Sake, try the white plum sake (I am not entirely sure the name). Reasonable omakase deals. If you are more of an experienced sushi lover and willing to try something that is not highly pricey, this could be a great option. Also, the location is not too far off from Bond Street Station.

Overall quite good! All the sushi is very nicely prepared and presented—very tasty. I did the full omakase at the counter, but I also included a photo of some table-service preparation that looked equally good! The quality of everything is excellent; I don't think you'd be disappointed. The variety of fish is decent, but I was a little surprised to not see uni anywhere, nor many traditional Japanese fish—no kinmedai, kurodai, nodoguro, shima aji, or anything like that. They do have some daily specials, including some domestic caught fish, which is nice. The vibe at the sushi counter came across to me as a bit... distant? Cold? If you prefer that, this is your place. I enjoy when it feels more engaged and welcoming. Nice selection of Japanese whiskey - certainly a plus. For a nice area of a major city I think the price point of the omakase is totally reasonable. You just need a booking at the sushi counter and it's an option. All good stuff and worth a shout, just a bit short of what I was hoping for.

Consistently excellent Japanese food at a decent price for London.

Super authentic Tokyo eatery in the heart of London; Excellent fish, large sushi knives, and epic Japanese chefs. Well done.

This is the best sushi I have eaten anywhere. The sourcing and preparation of the fish is comparable to the finest available in Japan. And the service was top class. I can also recommend the fabulous Black Chalk wines which complement the food perfectly.

A criminal restaurant with honesty, flavors that you will enjoy even after you finish eating I advise you to ask: The sashimi wagiu comes with 3 pieces of meat and the wagiu has an A5 and you notice this thing all the time, it's legendary. California roll sushi, light and delicious

Cubé, a Japanese sushi restaurant in Mayfair, exceeded expectations during our lunch visit. We opted for the sushi lunch set, which offered both quality and affordability. The atmosphere was welcoming, and the service was attentive.

Ngl absolutely the best sushi place in London!! :)

Hands down my favourite Japanese food in London. Any time I'm in the area it's a must eat. For the price, their sashimi and sushi cannot be beaten (anywhere in Europe/UK). If you are an omakase connoisseur, there are some options that compete at maybe triple the price, otherwise there's only Cubé! Rice bowls are excellent and so is the beef. Other dishes are excellent too. Love the chicken karaage here, light (not too oily) yet perfectly crisped. Service is extremely friendly and attentive.

Not an official review of the restaurant unfortunately, but a huge thank you to the member of staff (man) who helped me when I was unwell today. The compassion and care he showed was incredible in what was a very embarrassing situation, I will definitely be coming to try and recommending to my friends based on the phenomenal (not even a customer) service today. Thanks so much again.

What an absolute gem. In a sea of mediocre or ludicrously expensive London sushi restaurants, Cube stands out as not only excellent, but a great value as well. An unfussy - but still charming - interior is the backdrop for easily my favorite sushi meal I have had in London. Definitely recommend sitting at the counter and going for the omakase which is a steal for the quality on offer at £108. The sake list is also top notch and we received excellent guidance from Shunpei in selecting a truly delicious bottle to pair with our dinner. In short, everything about the evening was eminently enjoyable. I would highly recommend Cube!

Good was really nice and the service was good too- would definitely recommend anyone to try the mango sake, it was really delicious

Probably the best omakase in London

Just incredible, we loved everything about this place. Amazing food and flavours, lovely service and a calm atmosphere. Highly recommend the counter seating to see the beautiful fish and the chefs at work.

A real Japanese restaurant. Cooks from Japan. Fresh fish. But the Restaurant is very small, not at all elegant.

There is always one store that you will never forget after eating it, and this store has that charm. Both the floor service and the sushi chef are very considerate and attentive. Every time I come here I eat Omakase, the chef always surprises you. The sashimi is really fresh and impeccable.

Our favourite omakase in the world, including having been to Japan!

A very top site with very good quality products, a menu with classic and modern opinions and a service of 10 👌 I discovered it in the London guide of Velada app 📲

This was my having omakase sushi, sitting up at the bar. It was magnificent. Every bite was an adventure, providing balance of flavours, textures and temperatures. It was also just the right amount of food. From the dishes the chef gave me, favourites were the scallop, snow crab and spider crab, and otoro fatty tuna nigiri. A special experience that I won't forget any time soon.

Very nice sweet authentic restaurant

We did the omakase menu last week. It was without doubt one of the best meals I’ve had in London. Ben (sushi chef) went through each of the courses explaining the provenance. The sake was also great.

Amazing service and great quality of food. Truly authentic Japanese food served by Japanese people

nice lunch bento, very good service and friendly staffs and chefs. sashimi are big and thick cut.

Tucked away near Bond street station, off Oxford, this is hidden gem. Reminds of the small row restaurants in Tokyo with flag signs outside. All kinds of supef fresh sashimi, nigori, sushi, etc made at the counter in front of you by the pros! Must visit for Japanese food lovers

Expensive but the omakase was terrific. Worth coming here once in a while for a treat.

Excellente, the Cubé keeps is promises.

Best Japanese restaurant I've tried in London so far. Really good food with fresh seafood.

Unfortunately the restaurant is too commercially run, rather than focusing on serving the best quality sushi to customers. All the chefs during lunch time are trained by the Japanese head chef, they are friendly but technique is not on par with high end sushi. To be fair, price is cheap for omakase, the issue is more around the freshness of the fish (mostly around toro), ingredients quality and cutting techniques. I liked my sushi chef, very friendly. However, the other service staff can be more attentive. The first floor is a bit rundown and not very clean. All is all, below average food, despite cheaper price point, not worth it.

Japanese food is authentic, as if I were in Osaka or Tokyo. The service is excellent. The sushi is fresh and delicious, and the rolls are the same. The miso lobster soup is delicious. Everything we ordered was amazing. You can order wasabi, which is much tastier than what comes in a sushi plate. The prices are reasonable.

Came here for a weekday lunch and had their lunch omakase. The lunch omakase consist of 10 sushi and 1 temaki with dessert. Overall there were some hits and misses for me - the botan shrimp was amazing but some of the latter like white fishes were alright. The omakase is priced quite decently and the fish are sourced from all over Europe. Personally would recommend coming to try the food. They have an extensive sake and wine list to choose from. The service was warm and friendly as well, and we enjoyed celebrating our anniversary here.

Went for my birthday a few months ago and this is still the best sushi I’ve had in London so far. Although it’s not cheap, the price is very reasonable for the quality of food and lovely service.

the food was fine. the fish was good quality but the dishes were nothing special and very expensive for what it is. the raving reviews are giving people have only had bad japanese food.

Excellent sushi bar near the heart of London. We specially enjoyed the prawn tempura rolls and the negi toro rills. The nigiris are also excellent and delicious — salmon and yellow tail recommended!

Date lunch with my wife. We haven’t had real sushi since leaving Japan and this place didn’t disappoint. Amazing quality

Amazing omakase dinner with highly attentive service - will come back!

We went there for NYE, and I am now finding excuses to go again. We got the omakase and enjoyed every single course. It was my partner’s first time having omakase and he was amazed. We especially enjoyed the wagyu nigiri and the prawn nigiri (we reordered them), the wagyu just melts instantly when you chew it and the prawn was so fresh and tender. The service was top notch, I would give 10 stars if I could. The sake was also very good. Chef Masa is a gift to the people of England. I’d eat there every day if I could. Unfortunately they didn’t have sea urchin that day, but who said it couldn’t be an excuse to go back again?

Great omakase experience sat on the chefs counter and trying many nigiri that I would never have thought to order. The scallops in particular were melt in the mouth and all the fish was incredibly fresh.

Holy SUSHI!!!! Visiting from NY and trusted reviews for a sushi place next to our restaurant and wow am I happy we did. It was AMAZING! From the melts in your mouth nigiri to the eggplant appetizer (must have). This authentic sushi spot is a must in London.

Still after few months, it’s the best in town Quality and service and presentation and price to value is amazing Some affordable genuine Japanese food in town Must come But must pre book

Arguably the best Omakase in London! The fish quality is incredible and the staff are fantastic!

It’s a horrible experience. We booked for 3 people at the counter and when we arrived we were put on to table service. When we spoke to the “manager” (guy with glasses) he told me it’s the best he can do and he blamed that we didn’t call in advance. Yeah that’s fine then we ok for it. After that we started dining and they served 5 sushi at once. Well that’s not OMAKASE is it? We raised the question and the so called “manager” start arguing with us saying we either take it or leave it because “that’s the best he can do”. All we wanted was a sushi to be served INDIVIDUALLY as we are paying for Omakase service but he just said no and not even apologized. This is 0/10 customer service and we had to drop out without finishing because we cannot digest food in that environment All the manager should have done is say sorry but he never did it. Arrogant manager. Not the chefs fault, they are lovely but the manager ruined it NEVER COME BACK AGAIN

High-quality japanese food in london Lunch deal was reasonable price to enjoy good japanese food🫶🍣

This was the best sushi I had in London, and I have been to dozens of sushi restaurants. The waiter and overall service was great. It really felt like being in Japan. Only thing that could have been better is the wait between first and second appetiser. Almost 20 minutes.

We recently tried this authentic Japanese restaurant in Mayfair! It was super tiny with a few tables and a large open kitchen counter. We really enjoyed being able to see all the sushi being prepared. We ordered a selection of nigiri, maki rolls and a few hot starters! Everything was absolutely delicious and could not fault. If you’re looking for authentic sushi be sure to check it out 🤭 Lots of love Instagram: @EatWithHanbe 🤍

I treated myself to lunch at Cube and wasn't disappointed. Ordered the Cube Tempura Bento delicious.

A small hidden restaurant. It feels like being in Japan… the food was great.

Fantastic little place tacked in a small street near to Bond Street. Quality of food is amazing, service is excellent. We will be back. Thank you

Top notch service. Went for lunch omakase set.

Amazing omakase experience, the staff were all very friendly and attentive. The highlight was watching the chef prepare the food in front of you, and having him explain each dish. Relieved to find some decent sushi in London, this is definitely the best we've found so far!

素晴らしいレストラン。 おいしいおまかせ。 とてもリーズナブルな価格

Probably the best sushi experience in town. Great value considering the superb quality! We had the yuzu yellow tail to start and lunch omakase + sushi set. Everything was just so so good.

One of the best sushi places in London. Really chill and quiet environment. The omakase is done well, I did wish there was maybe one or 2 more for the price, and as I felt that I was asked if I wanted to order more which rubbed me the wrong way just a little bit. But it's a minor point as it was still enough that I didn't leave hungry.

Best sushi I’ve had, combined with attentive but unobtrusive service. There are buzzier places to eat but if you just want exceptional sushi with no fuss then this is the spot. The omakase was fantastic.

Brilliant. Great attention to detail and would absolutely recommend the chef’s Omakase - thank you for a wonderful evening!

Phenomenal and elevated sushi restaurant. Items are simple but of great quality and taste. Cold appetizers we had the Salmon Tosa tsukuri ponzu sauce (phenomenal and I recommend keeping the sauce for dipping sushi if you’re feeling crazy) as well as the Tuna Tataki. The chicken karage is incredibly juicy and comes with a great sauce. Salmon avocado ( fish was good but avocado was not ripe and a bit hard. Still did not detract from the experience and would order again) best sushi piece was the Toro taku with pickled idk what but it was great. Try one of the sweet sakes also !

Amazing omakase at a reasonable price. Love the quality of sashimi, especially wagu beef and fatty tuna!

Amazing omakase experience. Worth every penny.

Was absolutely delighted with the evening Omakase here. One of the easiest 5/5’s I’ve ever given a place.

I’ve been to many Japanese places and Cube probably can be top3 in London. Super attentive service and detail oriented, without making you feel uncomfortable, just the right balance. Starters and nigiri are amazing. Will come back and try the Omakase menu for sure. Deducted 1 star for atmosphere as the toilets are unisex and I went in after a dude who made a mess….

Had an excellent omakase for my birthday here. I really like the tuna and wagyu nigiri. The staff was kind and friendly. The restaurant has cozy vibe which I love. Everything was perfect. Will definitely come back.

Best sushi in London! Amazing choice of fish with completely unexpected species such as abalone, very talented chef and everything is top quality - as fresh as it can be

Absolutely amazing food. My favorite Japanese restaurant in London. The seared otoro nigiri is not to be missed. The service is phenomenal what with the friendliest staff. 11/10 highly recommend

This place is one of, if not my favourite, Japanese restaurants in W1. Always a winner. The food is just fabulous here. 🥢🍣🍤🍱

I visited on Saturday and had the omakase menu, absolutely the best sushi experience I've ever had. Delicious food and excellent service

This is proper Japanese food, delivered with precision by the sushi chefs and the staff. What is so wonderful is the joy with which one is greeted. Huge smiles, proper Japanese protocol. After 30 years in London this to me is the most incredible find.

Intimate spot located in a side street just off New Bond St in Mayfair. Sushi here is top quality the selection of tuna nigiri were extremely tasty, fresh and perfectly seasoned, Tonkatsu was crispy and tender served with a tasty sauce. The maki were also delicious, fish was fresh; rice to filling ratio was on point and the nori was clearly high quality. Matcha lava cake was delicious and paired perfectly with the ice cream. Staff were extremely friendly, attentive and behaved with professionalism. Overall we had a great experience here and I would very much like to return for Omakase, to experience a greater selection of this fish and to observe the best their chefs can offer.

There should be more effort put into the ambiance for £100+ per person. Please DO NOT come here if you want to have a nice night out. Once you enter, the restaurant is so messy and looks nothing like the pictures. The food/service is ok but 0 for atmosphere. Not worth the price at all.

Awesome food and service! Thank you for a lovely evening. :)

This is one of my favourite restaurants in London and I have been here probably around 10 times. The Omakase is excellent - you get 2 incredible appetisers (tataki and tempura), their fried dishes are perfectly hot, crisp and flavourful. Their fish selection is impressive, I have come here multiple times to have their Omakase and every time it has been impressive. £108 for an Omakase if an extremely reasonable price, especially in London! Even their a la carte dishes are fantastic, their tempura dishes are phenomenal and keep an eye out for their seasonal specials, they’re all brilliant. Ryo and the team have been very welcoming and accommodating and every time we visit we enjoy it thoroughly!

Fancy & high-end sushi restaurant in London. Seating is usually pretty limited so make sure to get a reservation if you want to eat here. If you're feeling adventurous, try the hot sake! Food is excellent but definitely pricey. If you're a fan of sushi, this is definitely worth a visit. The sushi was excellent, service was good, and the overall experience was lovely.

Cubé is the real deal. If you are looking for an authentic Japanese sushi experience, then look no further. Perfect for business meals, family gathering or for an intimate dinner-for-two! The restaurant isn’t large but it has a lovey peaceful atmosphere that works for any occasion. The service team here are friendly and attentive. I had both the nigiri sushi and several tempura dishes. Everything was executed with precision as one would expect. The taste was excellent. I’ve been to several Japanese restaurants in London and I can confidently say that the quality and experience of Cubé is one of the best. I will be back for more!

Лучший суши бар, который я посещал вне Японии. Только суши и сашими. Атмосфера от настоящей японской не отличается. Бар очень маленький - надо резервировать. 100% стоит идти.

I visited last week and it did not disappoint! Just wow

Pretty average food. Only one dish that was in any way special. Lovely staff though

What an amazing dining experience. Food was exceptional and matched by the friendly staff. Will definitely be back..

Lovely, cozy decore. Brilliant and friendly service. Honestly wish I got our server's name, he was so nice, explained the menu well and had great energy. The food it self was excellent. The Yellow tail sashimi, wagyu steak slices and spicy Tuna Negiri were Honestly solid 9.2/10. Will definitely go back. Perfect for a date or a mate.

I don’t usually write reviews, but this is one that I have to get off my chest… My partner and I both experienced terrible food poisoning after eating here. We contacted their manager in goodwill to inform them of the situation. Throughout the entire email communication chain, they did not apologise nor own up to their fault once. After almost a week, Kenta asked us to provide stool samples (which by this time would have given inconclusive results anyway). In his own words “I do not think there is any negligence in that nor making your complaint invalid.” DO NOT COME HERE, unless you you want to get food poisoning and humiliated to jump through hoops of stool sample and investigation in order for them to accept responsibility!
