Reservations · Delivery · Takeout · Outdoor seating

Cubé delivers an authentic, high-end Japanese omakase experience in Mayfair, with standout fish quality and attentive service, but at a premium price and with occasional service inconsistencies.

Why it gets an A- for overall quality

Cubé delivers exceptional fish quality and authentic preparation paired with attentive, knowledgeable service, positioning it competitively with London's respected sushi destinations. However, inconsistent execution in set menu contents and occasional preparation issues prevents grade A territory, while isolated food safety concerns and cramped spacing temper the premium experience. A strong choice for serious sushi enthusiasts willing to navigate variable service pacing and premium pricing.

Restaurant Summary

Cubé stands out as a premium Japanese dining destination in the heart of Mayfair, offering an omakase experience that rivals some of the best in London. Diners consistently rave about the exceptional quality of the fish, with many noting that the freshness and presentation are on par with top establishments in Japan. The intimate counter seating allows guests to watch skilled chefs at work, while the staff's attentiveness and detailed explanations add a personal touch to each meal. While the ambiance is understated and the space can feel a bit tight, the focus here is firmly on the food and the craft behind it. The culinary approach at Cubé is rooted in tradition with subtle contemporary flourishes. The menu features classic nigiri, sashimi, and maki, alongside premium offerings like A5 Japanese wagyu and foie gras don. While not highly experimental, there are enough creative touches to keep things interesting for seasoned sushi lovers. This is a place for those who appreciate the nuances of Japanese cuisine and are willing to pay for top-tier ingredients and technique. Expect moderate portions and a price tag that reflects the quality and location—this is a splurge-worthy spot for special occasions or serious sushi fans. For families with children, Cubé may not be the best fit. The menu lacks explicit kid-friendly options, and the adventurous flavors, premium pricing, and formal atmosphere are better suited to adults or older children with adventurous palates. While a few families have dined here, reviews suggest that the experience is not tailored to younger diners, and the absence of a children's menu or simplified dishes means picky eaters may struggle to find something suitable. If you're seeking a relaxed, family-friendly Japanese meal, there are better options elsewhere in London.
