Behind the Bookcase: A Taste of Luxury at Síbín Speakeasy, Whitehall
4.0 out of 5.0 stars
London is full of clandestine bars, some genuinely hidden, others merely dimly lit with a penchant for velvet curtains. The real trick is knowing which ones are worth the effort. I recently stumbled upon Síbín, a rather splendid speakeasy tucked away inside the five-star Great Scotland Yard Hotel in Whitehall, once the famed headquarters of London’s Metropolitan Police. Behind an unassuming entrance and a bookcase that conceals a secret button (yes, really), Síbín reveals itself as a slick, low-lit hideaway that feels both exclusive and quietly confident. It’s not shouting for your attention – if anything, it’s politely whispering that you might want to stay a while.
Step through the secret door, and you’re greeted by a space that feels both luxurious and inviting. The lighting is low and flattering—the kind that makes everyone look just a little more interesting—and the room centres around a beautifully designed long cocktail bar in wood, marble, and quiet confidence.
Burnt orange and teal cocktail chairs add a splash of rich colour against the dark wood panelling, offering comfortable perches from which to sip, swirl, and survey the room. Look up, and the ceiling catches the eye: it’s covered with over a thousand opaque glass bottles, creating a soft, diffused glow that adds a touch of theatre without tipping into excess. Shelves and cabinets line the walls, stacked with an impressive array of speciality whiskies from around the world. It’s part drinks cabinet, part treasure trove.
Here, you’ll find a bar that takes its cocktails seriously but not solemnly. The menu leans into innovation without veering into gimmickry, and the service is the kind that makes you feel like a regular even if it’s your first visit. Síbín is one of those rare London spots that manages to feel both like a discovery and a well-kept secret. And isn’t that what we’re all looking for?
Síbín – named after the Irish word for home-made whisky, nods to the old illicit drinking spots where spirits flowed freely, if not entirely legally. These days, there’s no need for secrecy (beyond the bookcase, of course), but the spirit of quiet rebellion still lingers.
While heritage whiskies remain central to the concept, the bar now caters to a broader crowd with a well-curated selection of premium wines and Champagnes. There are five signature cocktails, each designed to appeal to a range of tastes – whether you lean towards something smoky and spirit-forward or prefer your drinks lighter and more citrus-led. For those who like a familiar favourite, the menu also features clever twists on the classics.
The cocktails at Síbín are named in keeping with the speakeasy theme, and our first sips of the evening set the bar high. The Shebeen was a standout – a clever combination of Laks Whiskey Reserve No. 7 (and at Síbín, they really do know their whiskies), eau de vie, Campari and pamplemousse bitters, served over a honeycomb ice cube in a satisfyingly weighty tumbler. A grown-up drink with layered charm: bright, zesty top notes, warm whiskey undertones, and a bitter streak from the Campari that keeps things perfectly in check. Complex, balanced, and entirely moreish.
The Clandestine came tall, over a skyscraper of ice – a vibrant mix of Tromba Añejo and Casamigos Mezcal Joven, lifted with elderflower, grapefruit and citrus. It packed a smoky-meets-sparkling punch: a flicker of chilli heat, a hint of floral brightness, and that unmistakable mezcal edge. Dry, elegant, and smoothly drinkable.
The food menu at Síbín is designed for effortless snacking alongside your cocktails, and it delivers beautifully. From the small plates, we tried a silky mushroom pâté, rich and creamy, amusingly shaped as a moustache, paired with a tangy chutney and slices of grilled brioche – simple, but deeply satisfying. Then came delicate little blinis topped with thinly sliced octopus, a touch of caviar, and a light onion dressing, a surprisingly elegant combination that worked like a charm.
Also perfect for sharing: a well-curated British cheese board featuring Montgomery Cheddar and a perfectly ripe Brie, served with tangy chutney and crisp sourdough crackers. Alongside it, a generous British charcuterie selection with slices of Capocollo and other delicacies – simple, high-quality ingredients, thoughtfully presented.
Next, I chose the 6 O’Clock – named with reference to the early bar closures introduced during the First World War, a policy aimed at boosting wartime productivity and, somewhat ambitiously, public morality. Happily, there’s nothing austere about this cocktail. It’s an elegant, moreish swirl of Tanqueray Ten, yuzu, chamomile, and vetiver gris, served with a touch of drama – a delicate bubble perched on top, releasing a wisp of fragrant smoke as it bursts. Light, floral, and quietly sophisticated, it’s the kind of drink that feels almost too easy to sip.
The Bootlegger was another hit – an intriguing blend of Plantation Pineapple, Discarded Banana, apple, saffron, Cadello, and bitters. It packs a real punch, with bold rum notes balanced by tangy citrus and a subtle spice in the background. My rum-loving companion was instantly won over.
Finally, the Nightcup – served charmingly in a teapot. A blend of Tromba Añejo, Casamigos Mezcal, elderflower, Pol Roger, grapefruit, and citrus, it was bright, complex, and very drinkable. That said, it almost had me wishing it were warm; something about the teapot presentation makes you expect a comforting brew. Still, temperature aside, it was a clever, well-balanced finale with a gentle fizz and a smoky-sweet kick.
Síbín is a hidden gem in every sense – a clandestine destination tucked inside what was once London’s most notorious police headquarters, now transformed into a stunning five-star hotel. Here, mixology meets theatre, with a splash of alchemy and a twist of decadence. From the secret bookcase entrance to the expertly crafted cocktails and elegant small plates, it’s a place that delights in the details and rewards those curious enough to seek it out.
Sibin regularly hosts exclusive events such as cocktail masterclasses and weekly live jazz evenings.
