The Mayfair Underwater Fantasy and Modern Art Collection

The aesthetic at Sexy Fish defies conventional London restaurant design, immersing guests into an opulent aquatic wonderland from the moment they step off Berkeley Square. The dining room features an extraordinary collection of original contemporary artwork, highlighted by bronze mermaid sculptures cast by Damien Hirst and monumental glowing silicone fish lamps designed by legendary architect Frank Gehry. Behind the expansive bar stretches a monumental 13-foot bronze crocodile sculpture, illuminated by back-lit iridescent pink onyx that casts a sultry glow across the dining floor.

Polished dark parquet floors reflect light from bespoke glass chandeliers, while guests settle into curved leather banquettes finished in rich shades of burnt orange and deep coral. A live DJ booth anchors the room, spinning rhythmic deep house and tribal beats that build momentum throughout the morning. During Halloween weekend, the venue takes this theatrical foundation even further, adding elaborate oceanic phantom installations, costumed performers, and dramatic dry-ice presentations that make every table feel like center stage. The atmospheric lighting shifts subtly as the afternoon progresses, creating an immersive fantasy world.

Decadent Lobster Benedict and Crispy Duck Salad

The weekend brunch menu showcases modern Japanese and pan-Asian techniques applied to premium seafood and meats. A signature highlight of the morning is the Lobster Eggs Benedict, priced at £28, which elevates the traditional brunch classic into pure luxury. Succulent native British lobster tail meat is gently butter-poached and layered over toasted brioche rounds, crowned with poached Clarence Court eggs and draped in a vibrant yuzu-infused hollandaise sauce. The subtle citrus acidity of the Japanese yuzu cuts through the rich egg yolk and butter, delivering a clean, bright finish that diners remember long after their meal.

For a refreshing contrast of textures, the Crispy Duck and Watermelon Salad, priced at £24, remains one of the kitchen most requested dishes. Shredded roasted duck meat with deeply caramelized skin is tossed with chilled cubes of sweet red watermelon, toasted cashew nuts, fresh mint leaves, coriander, and pomegranate seeds. Dressed in a complex sweet-sour hoisin vinaigrette with a hint of red chilli heat, the dish delivers an invigorating burst of sweet, savory, and crisp sensations that cleanses the palate between rich courses. Table parties regularly order multiple bowls to share across the table.

Caramelised Black Cod and Themed Seasonal Libations

Diners extending their brunch into a multi-course afternoon feast frequently anchor their table with the celebrated Caramelised Black Cod, priced at £42. Marinated for hours in sweet Saikyo white miso, mirin, and sake, the Alaskan black cod fillet is roasted over intense robata charcoal heat until the exterior glazes into a smoky, dark amber caramel while the pearlescent flesh flakes away in buttery ribbons. It arrives presented on a charred bamboo leaf with pickled ginger shoots, representing the pinnacle of robata craftsmanship in central London.

Beverages at Sexy Fish match the high-octane culinary energy, boasting an imaginative list of handcrafted morning cocktails, premium sakes, and prestige Champagnes. During Halloween weekend, mixologists pour signature seasonal creations like the Ghost Mermaid cocktail, priced at £18, blending premium Japanese gin with lychee liqueur, blue spirulina, fresh lime juice, and a rim of shimmering black volcanic salt. Diners can also enjoy alcohol-free botanical coolers or freshly brewed sencha green tea served in cast-iron teapots, making the beverage program as memorable as the cuisine.
