A delicious lunch at the Atrium Restaurant in Mayfair
4.6 out of 5.0 starsAtrium Restaurant in the Mandarin Oriental, Hanover Square is an impressively large space at the heart of this modern luxury five-star hotel in Mayfair.
We were invited to review the three-course express set lunch, ideal for a break during a day of shopping on nearby Regent Street or Oxford Street. An elegant green marble sweeping staircase takes you down from the lobby entrance to the restaurant. Light floods in from the overhead glass skylight high above. The walls are adorned with natural wooden decorations, adding a sense of movement. The Atrium space was inspired by the elements – earth, wind, and water.
The seating is arranged around the sides of the floor. We tucked ourselves away at a table for two with a banquette on one side against the wall.
From the starter section, we chose octopus with ratte potatoes, Kalamata olives, confit tomato, and lemon parsley vinaigrette. The octopus was perfectly cooked, soft and tender. It was a generous portion, though not overly heavy.
We opted for a glass of the house wine to accompany the starter, a spèra, Siddùa vermentino from Sardinia, Italy. The sommelier made an excellent choice with this crisp and fresh white wine.
For my main course, I plumped for butcher’s cut skirt steak, English Wagyu, with hand-cut chips and béarnaise sauce. The meat was succulent and flavoursome; the chips had a delightfully crispy crunch, while the small pot of béarnaise sauce could have been a bit larger.
To accompany my main course, I chose a glass of the house red wine, Valpolicella 2025 from Allegrini, Italy. It was smooth and fruity and a great match.
My friend chose the lighter option: seared cod with spicy caponata, Trombetta courgette, and fresh basil. The cod was firm and well cooked, the caponata adding a spicy heat.
We moved on to dessert. I couldn’t resist the chocolate raspberry and lychee mousse; it was a beautifully presented dish. The thin, crisp outer chocolate shell, when cracked, revealed a light mousse sat upon a chocolate disk; the accompanying lychee sorbet was soft and refreshing.
My friend decided on the espresso affogato with hazelnut praline and vanilla ice cream. This dish was a delightful take on the traditional way an affogato is served. The hazelnut praline gave the dish a good texture; the amount of espresso was well judged, avoiding a pool of melted ice cream.
The service from the waiting staff was exceptional; we had lingered over our lunch enjoying an excellent meal.
To finish off our visit, we took the lift to the Hanover Bar, a swish rooftop bar with panoramic views over the surrounding area. The Hanover Bar is open to both hotel guests and walk-ins, with an extensive drinks list, including house cocktails as well as a menu of small bites.
It was difficult to choose a cocktail from the beautifully illustrated list. I chose the Serpentine, inspired by Hyde Park; it was a cool and refreshing combination of Everleaf marine, cucumber, mint, grapefruit soda with the added kick of oyster Adriatic gin.
My companion opted for the Regent, named after London’s cultural heritage. This long cocktail mixed Everleaf forest, elderflower, raspberry, lemon, and tonic, with the addition of Beluga noble gin. It was light and very drinkable.
The house-curated cocktails are non-alcoholic, with the option to add the suggested spirit if you choose.
The set-menu lunch at Atrium restaurant will not disappoint; it offers a strong selection of dishes prepared to a high standard with fresh, quality ingredients. The sheer size of the Atrium restaurant results in a stylish setting; it does, however, lack atmosphere. On the day we visited, other diners were businesspeople and shoppers. If you are looking for a cosy, intimate restaurant, this isn’t one for you.
Lunch is served in Atrium from 12.00 pm to 3.00 pm; two courses cost £36, three courses a reasonable £42. Add a glass of wine chosen by the sommelier for an additional £10. An à la carte menu is also available. The short set lunch menu includes gluten-free and vegetarian options to meet these dietary requirements.
