Cubé in City of London, Westminster

The staff are lovely and attentive. As soon as you walk in you are greeted by the chefs and servers, and our glasses never went empty. We ordered a salmon and avocado roll, a spicy tuna roll, and two servings of miso soup which were all delicious and great quality. Cubé isn’t cheap but the prices are not far off what you would expect for high class sushi elsewhere in london outside of Mayfair, and those locations certainly couldn’t match the atmosphere. All in all the overall experience is well priced. The restaurant is small so it may be a good idea to book in advance if you are wanting to go during a busier period or as a larger party

Wonderful food, really polite servers and incredibly fresh fish. It's a little pricey, but there are a lot of Japanese places in London that are just as expensive and not nearly as good.

Expérience inoubliable chez Cubé. Incontestablement le meilleur restaurant de sushis que nous avons testé. Le service était au top également, très sympathique. Mention spéciale pour la déclinaison de thon gras et la seriole, un délice ! Nous avons hâte d’y retourner lors d’un prochain passage à Londres.

Food was good. Kind service. Personally would have enjoyed more in a more decorated restaurant and themed music. I love Bob Marley and UB40. Just not my pick for a Japanese dinner.

Really lovely place, great food great service, loved the Steak, really looking forward to coming back again next time I visit the capital

*Food Poisoning* I type this review as warning to other customers, your wellbeing should be of the utmost importance when dining out. On the 20th Dec 2022, I dined out with my mother for a celebration meal. We ordered food and ate as normal, as we were leaving my temperature dropped and i felt tired. A sickness overcame me and acute diarrhoea. I managed to hurry to a nearby toilet and relieve myself. On recollection my mum, mentioned it looked like I had food poisoning, she saw a staff member who was preparing food with wet hands after a nearby toilet trip and wipe his nose prepping. I couldn't believe it. What followed for 5 days straight was diarrhoea and extreme stomach cramps. I took antibiotics, to which I had a bad side effect and it ruined my new years and Christmas. I am sure the chicken kaarage, chicken teriyaki, salad or maybe sushi caused my food poisoning. My stool sample tests came back from the NHS on 22nd Dec 2023, it detected Campylobacter. I reported this to Cube Mayfair and Kenta the general manager, who was more concerned about his own reputation than my wellbeing. He passed on my report to a food consultant who apparently is an expert on how my body works, an incubation period isn't necessary for everyone, my body reacted Swiftly right after the meal and before cube I was very healthy, strong immune system. The food consultant works for Kenta. Cube dismissed my claim and denied me a refund. They claim the restaurant is 5 stars and that's enough, how does that stop wet hands from a bathroom trip or staff wiping their nose, marinating the food with bacterium. So disappointed and still recovering, I have contacted food standards agency. Please visit with caution, i would not recommend a visit, stay home and cook better, safer food. Cube have ruined my 2023, they dont care about their customers. Food standards agency will be in contact.

Been there for a rather early dinner. The sushi was so tasty! The staff was very friendly and helpful. I would definitely go again.

Probabilmente il sushi più buono che ho mai mangiato. Freschezza del pesce ineguagliabile, le diverse varianti di Tonno sono incredibili. Carta dei vini discreta. Servizio formale e gentile, ambiente elegante. Prezzo da stella Michelin, ma tutto sommato per la qualità offerta, accettabile

My husband and I were excited to try this place and it was just amazing. Attentive staff and the food was so good that I can’t wait to go back. We had the Omakase menu for lunch and sat at the counter. It was a great experience being able to see the Chef preparation every single dish in front of us. It was a wonderful experience and this place is a gem. Highly recommend it!!!!!

As a non stop traveler and foodie… I regret not writing more reviews. Every now and then, a restaurant blows my mind and I feel compelled to write about it. This restaurant goes beyond that. Just to start… Their seaweed salad is not the preserved product that we have become used at sushi restaurants; it’s hand foraged, fresh and so healthy. No chemicals, artificial colors or flavors. My Omakase lunch included the very best choices from the chef. Fresh uni from Iceland, toro toro toro and a perfect marriage of other choices. I ate it before thinking to take a photo for the review! It’s a TINY place so RESERVE. As a bonus, the wine list includes really good French burgundies at reasonable prices. A bucket list sushi spot in London!

With a headline like this, why not 5 stars, you may be wondering. Well solely on account of my 3* rating for value: our dinner for three cost £75 a head (including a single bottle of sparkling wine). It's significantly cheaper to eat there at lunchtime but the drinks remain expensive throughout the day (£10+ for a glass of wine, £40+ for a bottle). It's a small restaurant but the layout is brilliant and not at all cramped. Food is prepared along one wall with some counter seats immediately in front. There are a couple of small tables near the entrance; at the rear of the ground floor several larger and more private ones. Further tables are available downstairs. The decor is smart with plenty of light wood. The clientele was an interesting mix of business diners (on the next table), friends meeting up, a couple of date couples and also two people dining on their own. Everything we ate was perfectly prepared and attentively served. We enjoyed our bottle of English sparling wine (which was no more expensive than the cheapest bottles of still wine). In a city littered with inauthentic Japanese eateries this was definitely the real deal and we enjoyed the experience very much.

Had omakase menu this week, this is the best sushi in Mayfair hands down. And fairly priced. Service exceptional, staff super attentive and friendly and very flexible with food variations.

I have been to countless Japanese restaurants in the City but non of them have impressed me as much as Cube Mayfair. It's clear that they place a high priority on both their ingredients and their attentive service. Having traveled to Tokyo I am so delighted to have found an authentic restaurant in London that reminds me so much of what I experienced in Japan. There's no doubt their rice is high grade Japanese and their sashimi is always ultra fresh and delicious. The service I have received from Misato-san at Cube is superior to what I have experienced at some of London's top Michelin restaurants. She managed to exceed my high expectations which is rare to find in London these days. Thank you so much Misato-san and the team at Cube for keeping your standards impeccably high despite us being in the middle of a pandemic. I wholeheartedly recommend this restaurant to anyone who loves authentic Japanese cuisine! If you get chance to order their delicious Matcha brownies I'm sure you won't be disappointed!

We had the Omakase menu and each piece of the sushi is sensational. Made with love and pride. The service is warm and non intrusive. We went to the bar downstairs after the fantastic food and continue with the some amazing cocktails. This is now my favourite Japanese restaurant with Japanese chef and Japanese staff. I will definitely be coming back. The quality of food is so good and yet the menu is so reasonably priced.

This is the best sushi restaurant in London. I will accept no opposition to this statement. Lovely place, lovely people. Top notch, class act.

This is my all time favorite restaurant! The food is amazing! I have been 5 times and every time I was amazed by the food quality. I have tasted most of the dishes on the menu and it’s excellent! They have a great variety of Sake as well. A strong recommend!

Kon’ichiwa! My name is Max Blackburn, but you probably know me by my other names... the oracle of the Maida Vale ... the Crypto Canary... The Nasdaq Nighthawk.... Or my personal favourite... *Sargeant Sashimi: Modern day defender of Cubé's honour.* I have made it my life’s work to protect Cubé from the evil forces of darkness (bad trip advisor reviews). Personally I find it disgusting that in the 21st century, people on tripadvisor leave negative reviews on my darling Cubé. Tbh i honestly don't know how people have the moral compass to do something like that. Anybody who thinks they can disrespect Cube will feel the full strength of my folded steel Katana” Cubé is the finest Japanese restaurant in the whole of W1 (central segment 16). The wagyu is so soft and buttery… its sends tingles through my rectum, something I can only compare to a long night in Kyoto with Jimmy Saville back in ’02. When I walk in to Cubé, the owner and my dear friend “Ira Shaimasse”, takes one glance at my 2010 Cartier Roadster and sends a bottle of 1942 straight to my table! He knows I’m here to spend some serious yen! I have adopted the role of Cubé night watchman… I will be patrolling trip advisor every night… stalking my prey of pro-fresh fresh sashimi and pro-tasteful decor lovers… stay away from Cubé…. Let that be a final warning….

The best sushi I’ve ever had in London. And very reasonable. Our meal for 4 cost me less than my meal for 1 at Zuma’s. A hidden gem.

Great authentic food, fab service and for Mayfair very well priced. Will be back. I especially recommend the yellow tail.

The food is to die for. If you eat beef, please try beef tataki, it melts in your mouth. Good customer service

Very serene and cozy ambiance in a quiet part of Mayfair. The unagi sushi, o-toro sashimi and soft shell crab karage stood out as excellent. Good service.

I’m don’t normally leave reviews for restaurants, however based on how much I enjoyed my experience here I just had to. The staff are polite, and the food is incredible - probably the best Japanese cuisine I’ve ever had. If you go, any dish is...

I had the pleasure of eating at Cubé last night and have to say it was one of, if not the best, Japanese restaurants I have ever eaten at in London. The food we had was a perfect mix between traditional staples, all of which...

The sashimi and sushi here was of the best quality. The service was friendly and attentive and the Covid procedures were all very reassuring. The sushi was beyond good, and also the drinks reasonable and the chicken karaage some of the best we have had....

I visited cubé for a Valentine’s Day dinner having no prior culinary experience with Japanese food. We visited based on friends recommendations and my girlfriend growing up in Asia. The whole experience was first class. The intimate restaurant has a lovely atmosphere and the service...

Good standard, a few misses, those more common in new places however not from an established restaurant (drinks menu forgotten, some confusing and confused staff...). To the food, miso aubergine nice but not the best I’ve tried, tuna, yellowtail and sea urchin very good quality....

Went for lunch and sat at the counter to have the set sushi lunchtime special. Each piece was made in front of us by a very skilled sushi chef and served by him as made. From the scallop , slightly seared to the beautiful eel,...

Having spent much of October in Japan, I was in London for the day and thought a quick lunch would be a good idea. I booked Cubé from the train and found it easily. The food was really excellent. A salmon teriyaki bento was as...

I went to this restaurant with my cousin on Monday 4th of November. We shared our food. The best dish was the aubergine dish and the sushi.

It's not as opulent as Sake No Hana or Ginza Onodera, it's not got a "high end" feel either, so if you want to dine in such an environment, this is for you particularly. Or shall we say, its very down to earth, unpretentious. We...

My boyfriend booked a table for lunch for my birthday, it was lovely, a little gem of a restaurant (we’d heard good things). The waitress was very attentive and the service was great. The open kitchen was interesting to watch, the decor of the restaurant...

Nice little place off Bond Street. It’s small and charming. Food is excellent. Sashimi pieces very generous and beautifully fresh. Katsu Sando nicely cooked. Wagyu beef tataki was nicely presented and perfectly seasoned. Service was attentive and friendly. Will definitely return

Choice of restaurants in the area is wide and there are 2 japanese alternatives (one chain, one other individual one) close by, BUT: what the chef creates at Cubé your mouth and dummy will love! Traditional sushi style and some alternatives. We had a sushi...

Excellent sushi and sashimi plate in this little hidden gem in the commercial heart of London but with a defiladed position which allows enjoying a peaceful break from the shopping. I suspect the chef’s tasting menus are excellent as well, judging from the numerous Japanese...

Traditional. No frills. Perfect sushi. If you want the real deal, instead of the nonsense you see at Zuma or Nobu, this is the place for you. Finest sushi in the land.

Kew-bay? Coo-bay? Kew-bee (or not Kew-bee)? I'd tried several different ways of pronouncing 'Cubé' before we got there, because I was a bit worried about going in and calling it the wrong thing - like my old friend who used to call Debenhams 'De-BEN-Hams' (complete...

All I can say is that this was a great dinner. Our waiter her was from Mexico was splendid. The food was great (sushi), but the ambiance was even better. Not all Japanese restaurants are created equally. This one’s a cut above. Good find!

This place is amazing. Dined their last night with friends and it was the best Japanese I have eaten in London. Generous and super-fresh sushi, and the hot dishes superbly executed with twists on traditional classics. The fact this place isnt booked out can only...

Great food with lots of attention to the service and presentation of each dish. We thoroughly enjoyed the dinner and are planning to visit again soon.

I can get a bit fussy when it comes to Japanese food and too often I’ve ended up with very generic flavours, slightly sub-fresh ingredients all hidden behind some pseudo flavours ... and then ending up paying an arm and a leg for it! Cube...

Very nice interior, casual but smart, you can see the chefs, and the service is timely and polite. Good choice of drinks too with a bar downstairs. Recommend sitting at the counter.

Had the omakase, sat by the sushi counter so you could see the chef prepare the food. Was a really great experience and the sushi was the best I've ever had in London. Really nice if you go on a special occasion especially

It is hard to find a genuinely good Japanese restaurant in London. You can easily spend a lot of money for decent food, but it will not be authentic and many hide the average quality of produce by adding many sauces and over modernising Japanese...

I recently visited Cubé with a group of friends and we had the most spectacular dinner. The restaurant was recommended to me by a colleague as the best place in central London to eat some stylish and tasty Japanese food. How right he was. Cubé...

Great little sushi spot tucked behind oxford street. I have had their express lunch menu several times, it is the best value sushi in town- generous portions of wonderful fresh sashimi. The service is efficient and courteous.

Thoroughly enjoyed my visit here. We had a mix of food. Some hot dishes, such as tempura and a selection of sushi and sashimi. All the food was very good and fresh. All the staff good and Japanese. A very enjoyable visit.

Excellent food in a lovely space. The staff were attentive, and the presentation excellent. A definite gem

A delightful cozy restaurant. We had a selection of small plates and every one was just right in flavour and presentation. The service was attentive without being intrusive. Cube also has a great selection of wine and sake. I highly recommend a visit and I...

The quality of the food was outstanding, incredibly fresh ingredients expertly prepared, with some striking dishes such as the sea urchin nigiri. We tried the below amongst many other dishes and were delighted with all of them. Appetisers: Seabass thinly sliced with ponzu sauce, yellowtail...

As someone who used to live in Tokyo, but also experienced first-hand the UK's growing appetite for all things Japanese (over the past 10/15 years), I had sadly become well-accustomed to culinary shortcomings here in London; this ranges from gimmicky, imitation sushi to the unbridled...

Seaweed salad and sashimi very very good!! I’ll come back. Only Down side: please don’t keep open the door to start closing out, while you still have customers in your restaurant.

I was in a work meal in a group of 4 people. We ordered a selection of starters and main courses to share and all were excellent. Staff were friendly but inattentive at times. Prices are not cheap (food probably worked out at £45 per...

Order the bento set with fried pork as main course. Sashimi is up to standard. Fried Pork is also also good. Staff is friendly. The only negative part is the rice, which is not as soft as usual Japanese rice. Overall, worth a try.

Just went for dinner with the family. Very friend and kind staff and one of the best sushi we have had. Menu is small but worth the visit

Worst service I have ever encountered!!!! Booked for a birthday and when we arrived the rude girl at the door told us the entire counter was booked out by a party at 20.30 so we had to sit at this tiny little bar table by...

I dropped by with my family for lunch and even though they were closing they took us in, they served us the best sushi and had the best attitude!! Will definitely come back!!

Perhaps you’re wandering the streets of London, after some shopping, and are craving Japanese food. But you are the kind of clientele who cannot be satisfied with a YO! Sushi but are also not looking to head to Nobu. Cubé is a truly tiny little...

Went for lunch here with my wife. Absolutely wonderful sushi and sashimi. I had to keep blinking to remind myself I was in London rather than Tokyo! Superb value as well - with the "early-bird lunch", which is available until 1pm. Will be back for...

Other half and I stumbled across this place while shopping and happened to be there whilst the early bird menu (12:00-13:00) was on. It was truly excellent; top quality sushi and great value. We’re already planning our next visit!

First visit for early dinner and chose Early Bird Menu which was great value given the quality of dishes, espacially sushi was fantastic even if only 6 pieces. Worth visiting.

Had excellent food,wine and service here! Would highly recommend! A true hidden gem, a beautiful place!

Taken by a London native here. Japanese food is not my usual choice when it comes to going out. Came highly recommended by him. Small place. Typical family run Japanese restaurant. The friend did the ordering and it was just amazing. The husband and wife...

Having visited numerous Japanese restaurants in London, we were pleasantly surprised by the quality of both dishes and cocktails and the fantastic value. The staff are very welcoming and attentive; they made helpful recommendations based on our picky tastes. The food was beautiful presented and...

I loved everything about this little place: the location, the few tables outside, the Spartan interiors that for me spotlight the beauty of Japanese aesthetic, the chef, the food and the staff. I came here for pre-theatre meal, and it was perfect for that, 15-20min...

Cube is, without a doubt, the best restaurant I've had the pleasure of eating at since I've been in London. The staff are incredibly friendly and attentive and the bartender made some of the best cocktails I've ever had. I went with a group of...

Lovely dinner and amazing sushi: we sat at the bar and loved the experience and the interaction with the sushi chef. Would unconditionally recommend it although found the price a little too high.

This is a small well run restaurant with seating upstairs and a bar area downstairs where you can eat at the bar or book a private cave - it's all very well set out and the cocktails are great. The Japanese 'old fashioned' was excellent....

Amazing food prepared right in front of you. Hypnotising to watch - very fast yet relaxed service. Would recommend to anyone. Both hot and cold food is absolutely delicious. Don't want to eat sushi anywhere else now...

The restaurant is quite small, comfortable and w a lot of blond wood and a mix of counter seating and small tables. The cooking is excellent! And some dishes are truly innovative and surprising - a shame that the staff were a bit distracted and...

We read about this place an evening before in one of the local newspaper. Being in the neighborhood of New Bond Street and just wanting to have a light bite for lunch we gave it a try. The place is small and neat ( them...

This restaurant was very quaint and I liked it very much. Perfect for my date and I. Food was lovely, I couldn't fault it. The service/waitresses were wonderful Thank you for making the evening a good one. Arigato

Went here for a Friday lunch. Given a hot hand towel on arrival which sets the scene for the service which was helpful and attentive throughout. We asked for some guidance on the menu and were brought several delicious plates including bento, sashimi, sushi, teriyaki...

This place was to be a ramen place and now transformed into sushi fine dining. Went and tried it with a foodie friend. The menu is interesting.

Visited for dinner and absolutely loved it! The decor is minimalist which gives it a lovely atmosphere. The food is amazing and it's great to be able to share all the dishes - means we could try out a lot of the food on the...
