Langosteria Restaurant London Review: Is Milan’s Cult Seafood Worth Booking?

August 16, 2026

Langosteria restaurant arrives in London with the confidence of a venue that has already been admired in Milan, Paris, Paraggi, Porto Cervo and St Moritz. It does not whisper its credentials. It enters The OWO dressed for dinner.

This is Italian seafood with fashion-world posture: raw fish, oysters, langoustines, blue lobster pasta, polished service and enough marble to make the bill feel inevitable.

The danger with international imports is that London receives the brand but not the soul. Langosteria, at its best, seems determined to avoid that. The seafood is serious, the room is glamorous, and the whole thing understands that fine dining sometimes needs a little theatre.

What Is Langosteria?

Langosteria began in Milan’s Design District in 2007 and has since become shorthand for a certain kind of Italian luxury: seafood, tailoring, serious wine and people who look as though they were born knowing how to order crudo.

The London restaurant is its first UK opening, set inside The OWO, the former Old War Office now home to Raffles London. The building has history, scale and a sense of occasion that suits Langosteria’s appetite for glamour. The food follows the group’s familiar formula: exceptional seafood, Italian technique and a contemporary international gloss. It is not rustic nor pretending to be a trattoria. It is a restaurant that knows exactly how expensive its prawns are.

The Atmosphere and Design

Langosteria’s London room has been designed to bring Milanese brio into The OWO’s imperial bones. The look includes silk wall coverings, Venini lamps, Verde Alpi marble, custom furniture and the brand’s signature red accents.

It is polished, but not cold. There is an open kitchen, which gives the dining room some useful movement, and the dedicated Whitehall Place entrance makes it feel like a destination rather than simply another hotel restaurant.

The crowd is likely to be part hotel guests, part London seafood enthusiasts, part fashion-week energy that took a wrong turn at Milan Linate and landed in Whitehall. This is not a casual room. The official dress code is smart casual, but the sensible interpretation is: make an effort.

The Menu

The menu is built around the raw bar and the sea. Begin with oysters, gambero rosso, langoustines or the full Plateau Royale if the table has accepted its financial destiny. Red tuna carpaccio is the clean, elegant opening; langoustine tartare with foie gras is the richer, more Langosteria move.

Starters continue the seafood theme. Tiepido di mare, a warm seafood salad, brings Italian restraint to excellent ingredients. Frittura Langosteria, with gambero rosso, langoustines and calamari, is less restrained and probably better for it.

Pasta is where the restaurant becomes easiest to love. Linguine with Brittany blue lobster is the obvious order, generous and glossy in the way expensive lobster pasta should be. Paccheri with sea bass gives the table something softer and more southern Italian in spirit.

For mains, black grouper chateaubriand is the showpiece, designed for sharing. Charcoal-grilled Dover sole offers a more classic route, while octopus with chorizo and purple potatoes brings a little smoke and spice. This is not seafood treated delicately for the sake of manners. It is seafood handled with confidence, money and a very good tailor.

Drinks & Wine

Wine is central to Langosteria’s identity. Expect a serious list with an Italian backbone, Champagne weight and enough ambition to turn dinner into a much larger decision. Cocktails are also treated as part of the performance. Start with something sharp, then let the sommelier steer the table towards seafood-friendly whites, sparkling wine or a richer bottle for lobster.

Who Is Langosteria Best For?

Langosteria is best for diners who want seafood with polish, glamour and a properly international crowd. It works for special occasions, client dinners, dressed-up dates and hotel guests who want dinner to feel like part of the stay. It is less suited to anyone seeking understatement. Langosteria is not modest, and it would be pointless to ask it to be.

Is Langosteria Worth Booking?

Yes, if you want one of London’s most glamorous new seafood restaurants and are comfortable paying for the privilege. Langosteria brings serious ingredients, Milanese confidence and a room that understands the value of spectacle.

The prices will not be gentle, and some of the glamour may feel imported rather than earned in its early months. But the seafood pedigree is real, and the best dishes sound exactly like what this building needs: lobster, oysters, Dover sole, Champagne and a little Whitehall theatre.

Book for dinner, start at the raw bar, and order the blue lobster linguine. This is not the place for restraint.
