After Dark Ranking
10 Addresses · Ranked by our editors · Updated 2026
London's hotel bars are where the city's cocktail culture lives: two of them have been named the best bar in the world, and several others have held the title's shadow for decades. These are rooms where the martini is treated as liturgy and the ice is carved like sculpture.
Our ranking weighs the drinks first — creativity, consistency, the quality of the classics — then the room: its light, its theatre, and whether strangers still talk to each other at the bar. Dress codes are soft-smart at most, though The Ritz-adjacent addresses expect effort. Walk-ins are possible at some, but the top three merit a reservation.
Mayfair
“The Connaught Bar — twice the world's best — where the martini trolley ritual remains cocktail theatre's high watermark.”
A legendary Mayfair address where heritage meets contemporary artistry. Home to Hélène Darroze's Michelin-starred table and the city's most storied martini bar.
Covent Garden
“The American Bar: the oldest surviving cocktail bar in London and still among its very greatest.”
London's first purpose-built luxury hotel, hosting everyone from Monet to Marilyn since 1889. Thames-side grandeur with the Savoy Grill, the American Bar and butler service as standard.
St James's
“The American Bar's clubby St James's cousin — ties on the ceiling, legends behind the stick.”
Tucked down a St James's mews, The Stafford pairs country-house calm with 380-year-old wine cellars and the American Bar's legendary hospitality. A clubby, discreet favourite of returning regulars.
Marylebone
“Artesian, the perennial award-winner — inventive menus and a room of purple-leather glamour.”
Europe's original grand hotel, presiding over Regent Street since 1865. Home to the Artesian bar, Roux cuisine at The Landau and a palatial Chuan spa beneath the West End.
Holborn
“Scarfes Bar — live jazz, caricature-lined walls and a library's worth of whisky by the fire.”
An Edwardian courtyard sanctuary moments from Covent Garden. The Mirror Room's afternoon tea and the Manor House suite define modern British grandeur.
London Bridge
“Gong, on level 52 — the highest hotel bar in Western Europe, with the skyline as the garnish.”
Western Europe's tallest hotel, floating between the 34th and 52nd floors of The Shard. Gong's sky-high cocktails and floor-to-ceiling sunrises over the Thames are pure theatre.
Covent Garden
“The Library Bar's converted courthouse grandeur — velvet, mahogany and beautifully built classics.”
The Bow Street magistrates' court reborn as London's most theatrical hotel, with a soaring atrium restaurant under a glass canopy. Library cocktails and Covent Garden's opera houses at the door.
Fitzrovia
“The Punch Room's oak-panelled intimacy — sharing punch bowls and Fitzrovia's most romantic booths.”
A design-forward landmark in a Georgian row off Oxford Street. Berners Tavern's art-crammed dining room is one of London's great evenings.
Mayfair
“Claridge's Bar and the hidden Fumoir — Art Deco shimmer and the best-dressed room in Mayfair.”
The jewel of Brook Street, adored by royalty and Hollywood alike. Art Deco grandeur, legendary afternoon tea, and service that borders on clairvoyance.
Mayfair
“The Bar at The Dorchester — deep leather, serious martinis and Park Lane's most comfortable hour.”
The Park Lane legend, freshly reimagined after its most ambitious restoration in decades. The Promenade's afternoon tea remains London's most coveted table.
