Aki is an authentic Japanese robata restaurant at 1 Cavendish Square, Marylebone, London W1G 0LA. Powered by traditional binchotan charcoal, our robata grill menu features caramelised black cod (£38), chicken yakitori (£14), Lumina lamb cutlets (£32), and certified Kobe beef sirloin.


Finding an exceptional robata restaurant in London is a search for balance, heat, and restraint. While charcoal cooking has ancient origins in Japan’s northern coastal villages, elevated robatayaki requires pristine ingredients and steady radiant embers. At Aki, set within a Grade II-listed former bank in Cavendish Square, robata is prepared over white oak binchotan charcoal and integrated into an expansive Japanese fine-dining menu featuring sushi, sashimi, and our vault cocktail lounge, Kiyori.

Robata 101

What is robata? The art of Japanese binchotan charcoal cooking


Robata, short for robatayaki (炉端焼き), translates literally to “fireside cooking”. Originating with northern Japanese fishermen who grilled their catch over hot embers on communal hearths, robata has evolved into one of Japanese gastronomy’s most refined techniques. Unlike standard Western grilling, robata relies on radiant heat rather than open flame flare-ups, preserving the natural juices and delicate textures of seafood, meats, and seasonal vegetables.

Why authentic binchotan charcoal matters:

  • Pure radiant heat: Japanese binchotan burns cleanly at steady, ultra-high temperatures without throwing flames or soot
  • Caramelisation without bitterness: Seals exterior surfaces instantly, creating crisp edges and natural umami without harsh acrid smoke
  • Flavour enhancement: Pairs naturally with tare marinades, shio koji, den miso, and yuzu seasonings
  • Culinary versatility: Allows our chefs to grill black cod, yakitori skewers, Lumina lamb, and certified Kobe beef to exact internal temperatures

What makes Aki one of London’s premier robata restaurants

While London offers casual izakaya counters, Aki delivers a fine-dining robata experience that combines traditional Japanese grilling craft with an architecturally striking central London setting.

The fire

Authentic binchotan embers


Our robata grill is powered by pure binchotan charcoal. Its steady infrared heat cooks proteins evenly from within while imparting a subtle, savoury depth that ordinary charcoal cannot replicate.

The menu

Beyond a single-focus grill


Robata at Aki is part of a complete Japanese menu. Guests can begin with sashimi or nigiri, progress through robata skewers and seafood, and finish with certified Japanese Wagyu.

The seasoning

Traditional Japanese marinades


Shio koji, den miso, fresh yuzu, aged tare, nuka pickles, and house-made furikake provide nuanced depth. The charcoal fire elevates these fermented seasonings rather than overpowering them.

The setting

Grade II-listed heritage room


Located at 1 Cavendish Square, Aki occupies a grand former bank. High ceilings, classical stone, contemporary art, and an atrium glass roof provide a sophisticated atmosphere for dinner.

The cellar

Curated sakes and fine wines


Smoky robata dishes pair naturally with artisanal junmai sakes, Japanese draught beers, textured white Burgundies, and structured reds chosen by our sommelier team.

The location

Marylebone & Oxford Circus


Situated in Marylebone, Aki is a two-minute walk from Oxford Circus and Bond Street (Elizabeth Line) stations, making it an ideal central London dining destination.

How to curate an authentic robata dinner in London

First course

Begin with raw clarity


Start with sashimi, nigiri, or light crudo. The clean salinity of fresh seafood and real wasabi awakens the palate before charcoal dishes arrive.

From the grill

Balance rich and light cuts


Combine robata asparagus or tenderstem broccoli with chicken yakitori, caramelised black cod, or Lumina lamb to ensure textural variety across the table.

Wine & sake

Pair with charcoal depth


Crisp Japanese beers and junmai sakes match yakitori and chicken wings. For black cod, opt for textured white Burgundy; for lamb and wagyu, select an elegant Pinot Noir or Nebbiolo.

After dinner

Descend to Kiyori lounge


Complete your evening downstairs at Kiyori, Aki’s cocktail lounge inside the original bank vault, featuring rare Japanese whiskies and live DJ sets.

What to drink with robata grill dishes

Binchotan grilling yields caramelisation, smoke notes, and intense umami. The ideal beverage pairing cleanses the palate while complementing savory marinades and aged soy glazes.

Sake and beer

Crisp, refreshing balance


Chilled Japanese lager cuts through the richness of chicken wings and tare-glazed yakitori. Fuller-bodied junmai and ginjo sakes harmonize with miso-marinated fish.

Texture for miso and seafood
