The Mandarin Oriental Mayfair, which opened in 2024, features a unique signature fan designed by the late Vivienne Westwood. This was Westwood's final project before she passed away in 2022 at the age of 81. The fan is notable for being the first to be designed and made entirely in Britain for 70 years for the Mandarin Oriental group.
Located in Hanover Square, the hotel is described as having a "boutique" feel, contrasting with the Mandarin Oriental Hyde Park. It is a new build designed to blend with its surroundings. The property includes 50 rooms and suites for visitors, alongside 77 residences.
The hotel offers amenities such as a spa with a swimming pool, vitality pools, a steam room, and a sauna. Dining options include the Atrium Restaurant, which serves Asian fusion cuisine, and Mazarine, a French restaurant focusing on seafood. The Hanover Bar, located on the rooftop, provides an outside terrace with views of the London skyline.
