Chef’s choice, your rules: presenting the social Omakase in London

We have all been there. You are sitting at a Hinoki wood counter, possibly in Ginza, possibly in Mayfair. The lighting is low, the silence is heavy, and a chef is placing a single piece of nigiri in front of you with the gravity of a religious offering. You eat it. He watches. You nod appreciatively. He nods back. And so it goes for two hours.

It is beautiful, of course. It is art. But sometimes, you just want the food without the performance anxiety.

There is a growing feeling among London foodies that the Omakase experience has become a little too rigid. You want the incredible culinary excellence, the trust in the chef, the seasonal ingredients, the surprise… but you also want a night out. You want to lean across the table, share a joke, and maybe even order a second round of cocktails without feeling like you are desecrating a temple.

This is where Aki steps in.

We have taken the traditional concept of Omakase (literally in Japanese, “I leave it up to you”) and stripped away the stiffness. Located in our Grade II-listed sanctuary in Cavendish Square, we offer what we like to call the social Omakase. It is a dining experience built on Japanese precision, but fuelled by London energy.

It is for those who know the difference between chutoro and otoro, but who also believe that fine dining shouldn’t feel like a library.

Omakase at Aki: social, surprising and fun

In its purest form, Omakase is an act of trust. It is a contract between the chef and the guest where you surrender your choice in exchange for their expertise. The problem with many London counters is that this contract often comes with a side order of isolation. The pacing is dictated by the kitchen and the seating arrangement makes conversation difficult.

At Aki, we honour the Japanese tradition of the chef’s selection while reimagining the delivery. Under the guidance of our Head Chef Mamadou Sankaré, we present our tasting menu not as a drip-feed of single bites, but as a spectacular, architectural platter.

This is the social Omakase: it arrives at the table as a centrepiece, a curated landscape of the day’s best catch designed to be shared. It changes the dynamic of the meal entirely. Instead of focusing silently on the chef, diners can focus on each other. You explore the platter at your own pace. You compare notes on the flavours. You take your time.

Chef Mamadou brings a unique perspective to this dining experience. With a background that spans many respected kitchens, he understands that culinary excellence is not just about what is on the plate, but how it makes you feel. His curation ensures you get the highest grade of fish available that morning, yet the service style allows the evening to flow naturally. It is the best of both worlds: the obsessive quality of a serious sushi counter with the relaxed intimacy of a private dinner.

The anatomy of our Omakase platters

Do not mistake “relaxed” for “casual”. While the atmosphere at Aki puts you at ease, the kitchen operates with the kind of rigour you would expect from the city’s most serious establishments. When you order the Omakase menu, you are getting a masterclass in sourcing and technique.

The platter itself is a study in Japanese technique. Whether you choose the 21-piece sashimi selection or the 32-piece nigiri showcase, every slice tells a story of provenance.

It begins with the fish. Chef Mamadou sources Portuguese Wild Blue Fin Tuna, a sustainable and deeply flavourful alternative to the standard market offerings. You will experience the full spectrum of the tuna, from the clean, iron-rich lean cuts to the buttery indulgence of o-toro (fatty tuna) that dissolves instantly on the tongue. Alongside this, you might find sweet Botan Ebi (giant shrimp), organic salmon, or the delicate crunch of Ika (squid), each chosen for its texture and freshness.

But a true culinary journey is defined by the details. At Aki, we serve fresh root wasabi rather than the powdered imitation found elsewhere. It brings a herbal, aromatic heat that lifts the fish rather than overpowering it. Perhaps most importantly, we brush our nigiri with our house-made 30-year aged soy sauce. This incredible elixir adds a depth of umami that young soy simply cannot replicate.

These are ingredients that command respect. The Kristal Ossetra Caviar adds a touch of salinity, while the uni (sea urchin) offers that distinct, creamy taste of the ocean. It is exquisite sushi without the pretence, allowing the quality of the produce to speak for itself.

Beyond Omakase: cocktails, atmosphere and DJs

The difference between a good meal and a memorable dining experience often lies in what happens around the food. In a traditional Omakase setting, the soundtrack is usually the chop of a knife or the hush of reverence. At Aki, we prefer a different rhythm.

As the evening progresses, our resident DJ curates a soundscape that builds energy in the room. It is vibrant enough to feel like a destination but intimate enough to allow for close conversation. This is Japanese spirit with a London pulse.

The freedom of our tasting menu extends to the glass as well. Without the rigid course-by-course structure, you are free to explore pairings that suit your palate. For the purist, our sake list offers a journey through Japan’s prefectures, from crisp junmai to complex, floral daiginjo styles that cut through the richness of the fatty tuna.

However, we also encourage you to look beyond the traditional. The complexity of our aged soy sauce and seasonal ingredients finds a surprising partner in Japanese whisky. A dram of whisky, served over ice, creates a bold contrast to the delicate sashimi. Alternatively, one of our signature cocktails adds a touch of theatricality that you simply wouldn’t find at a silent counter.

It is this flexibility that defines the Aki ethos. You can treat the platter as a serious tasting exercise with a flight of premium sake, or you can enjoy it as the ultimate accompaniment to a Friday night celebration with cocktails. The choice is entirely yours.

Lunch or dinner? An Omakase experience in London for every occasion

One of the greatest barriers to enjoying Omakase in London is the time commitment. A traditional multi-course service can easily stretch to three hours, ruling it out for anything other than a dedicated evening event. Aki’s social Omakase changes this equation.

Because the selection arrives as a beautifully composed platter, it fits seamlessly into a busy schedule. It has become a secret weapon for the power lunch crowd in Marylebone: a way to impress a client with culinary excellence and exquisite sushi without the risk of a long, drawn-out service interrupting business.

Conversely, by night, the lights dim and the platter becomes the anchor for a long, leisurely dinner. It is the ideal centrepiece for a romantic date or a gathering of friends, removing the “menu anxiety” of ordering for a group while ensuring everyone tastes the kitchen’s best work.

Whether you are visiting for a midday meeting or a late-night celebration, the consistency remains. You get the best of Chef Mamadou’s daily catch, prepared with uncompromising Japanese technique, served on your timeline.
