Mistress of Mayfair · Restaurant · London
Subterranean dining and late bar down the stairs on St James's Street
Mistress of Mayfair reveals itself at the bottom of a staircase at 48-49 St James's Street, a subterranean den of red velvet drapes, plush banquettes, and muted chandelier light that leans toward late-night Parisian intrigue. The basement concept opened in early 2024 and draws on the area's historic clandestine tunnels, building an intimate room around a central bar, with velvet booths along the walls and semi-private zones set aside for smaller groups.
The kitchen works modern Mediterranean cooking with French elegance, built for sharing across the table, with a raw bar and composed seafood plates alongside classic French technique and a considered dessert list.
The evening has an arc: dinner starts intimate, then the room shifts later into a livelier, more social pace, with select nights restricted to members after 11pm. Service stays polished throughout and suits a long, lingering meal.
The room runs Thursday and Friday from 7pm to 3am, Saturday from 1pm to 3am, and Sunday from 7pm to midnight, and is closed Monday to Wednesday. Dress is chic, polished evening wear. Demand peaks around Wimbledon fortnight, Royal Ascot, and the November to December Christmas party season, so those are the dates to book furthest ahead.
