London’s hotel bars aren’t just places to grab a drink-they’re experiences. Think velvet booths, live jazz humming under crystal chandeliers, and views that stretch across the Thames or over Hyde Park. You’re not just ordering a gin and tonic; you’re stepping into a scene crafted by mixologists who treat cocktails like fine art. And yes, the price tag matches the moment. But if you want the kind of night that sticks with you, these are the five hotel bars you can’t miss in 2025.
The Connaught Bar - Where Tradition Meets Innovation
The Connaught Bar in Mayfair has held a Michelin star for cocktails since 2019, the first in the world to do so. It’s not flashy. No neon, no loud music. Just deep leather, warm lighting, and a menu that changes seasonally with ingredients sourced from the hotel’s own herb garden. Their signature, the Connaught Martini, is stirred tableside with a choice of three gins and a whisper of vermouth. You’ll taste the difference: clean, crisp, and perfectly balanced. The bar team remembers your name, your usual, and even the way you like your ice. It’s the kind of place where a single cocktail feels like a private performance.
Sky Garden Bar - London’s Highest Lounge
At 140 meters above ground, the Sky Garden Bar inside the Walkie Talkie building isn’t just high-it’s surreal. The 360-degree glass walls wrap around you like a floating greenhouse. During sunset, the city turns gold, and the Thames becomes a ribbon of glass. The cocktails are inventive: try the London Fog, a blend of Earl Grey-infused gin, lavender syrup, and sparkling wine, served in a chilled coupe. Entry is free, but you need to book ahead-no walk-ins allowed. It’s popular with tourists, but locals know to come on a weekday after 7 PM for quieter corners and better service. This isn’t just a bar; it’s a vantage point you can sip your way through.
The Zetter Townhouse - Hidden in Clerkenwell
Nestled in a converted 18th-century townhouse, The Zetter Townhouse feels like stumbling into a secret society. The bar is tucked behind a bookshelf that swings open-yes, really. Inside, it’s dim, cozy, and full of vintage finds: leather-bound books, brass lamps, and a collection of rare spirits from the 1920s. Their Spiced Pear Old Fashioned uses pear brandy aged in sherry casks and a house-made cinnamon syrup. It’s rich, warming, and smells like autumn in a glass. The bartenders here don’t just make drinks-they tell stories. Ask about the 1930s absinthe spoon they found in the walls. You’ll leave with more than a drink-you’ll leave with a memory.
The Roof Gardens Bar - A Garden in the Sky
Overlooking Kensington, The Roof Gardens Bar sits atop the Kensington Roof Gardens, a hidden oasis of tropical plants, flamingos, and waterfalls. The bar itself is open-air, surrounded by banana trees and blooming orchids. In summer, you’ll sip a Champagne Pimm’s under string lights while watching peacocks wander nearby. In winter, heated blankets and fire pits keep the chill away. The cocktail list is short but brilliant: everything is made with fresh fruit, house syrups, and small-batch spirits. The London Bloom, a gin-based drink with hibiscus and rose petal syrup, tastes like a spring day captured in a glass. It’s the only place in London where you can drink a cocktail while surrounded by real flamingos.
The Bar at The Lanesborough - Timeless Elegance
Just steps from Hyde Park, The Lanesborough’s bar is pure old-world luxury. Marble floors, gilded mirrors, and a grand piano that plays softly in the evenings. The bar manager, Michael, has been here since 1998 and still hand-selects every bottle. Their London Sling is legendary: a mix of London Dry gin, elderflower liqueur, lemon, and a splash of soda, served with a single, perfect orange twist. It’s simple, elegant, and never changes. The bar doesn’t chase trends-it sets them. You’ll find diplomats, actors, and royalty here, all sipping quietly, never loud, never rushed. If you want to feel like you’ve stepped into a 1950s James Bond film, this is your spot.
What Makes a Hotel Bar Worth the Price?
These places cost more than your average pub. A cocktail here runs £18-£28. Why? It’s not just the alcohol. You’re paying for the atmosphere, the service, the attention to detail. At The Connaught, the ice is hand-carved. At Sky Garden, the view is free, but the experience isn’t. At The Zetter, the story behind the drink is part of the price. You’re not buying a drink-you’re buying a moment. And in London, where space is tight and time is precious, that moment is rare.
Pro Tips for Visiting
- Book ahead-especially for Sky Garden and The Connaught. Walk-ins are rare after 6 PM.
- Go on a weekday. Weekends get crowded, and service slows down.
- Ask for the bartender’s recommendation. Most have a secret menu or a seasonal special.
- Don’t rush. These bars are meant to be lingered in. Plan for at least 90 minutes.
- Some bars, like The Lanesborough, don’t take reservations for the bar area-arrive early and claim a seat at the counter.

Why These Bars Stand Out in 2025
London has hundreds of bars. But only a handful make you feel like you’ve entered another world. These five don’t just serve drinks-they serve atmosphere, history, and craftsmanship. They’ve stayed relevant not by chasing trends, but by doubling down on what matters: quality ingredients, trained staff, and unforgettable settings. Whether you’re celebrating a milestone, impressing someone, or just treating yourself, these bars deliver more than alcohol. They deliver a story you’ll tell again and again.
Are hotel bars in London worth the high prices?
Yes-if you value experience over cost. A £25 cocktail at The Connaught isn’t just gin and vermouth. It’s hand-carved ice, a mixologist with 15 years of experience, and a setting that feels like a private club. You’re paying for the atmosphere, the service, and the memory-not just the drink. For many, it’s a once-in-a-lifetime treat worth every pound.
Do I need to book ahead for these hotel bars?
Always. The Connaught, Sky Garden, and The Lanesborough require reservations. Even if you don’t need one, showing up without one on a Friday night means waiting an hour or more. Book at least 24 hours in advance, especially for rooftop or hidden bars.
Can I visit these bars without staying at the hotel?
Absolutely. All five are open to the public. You don’t need a hotel key. Just walk in-or better yet, book ahead. Some, like The Zetter Townhouse, are even harder to find without knowing the address, so check their websites first.
What’s the best time to visit for fewer crowds?
Weeknights, especially Tuesday and Wednesday, are quietest. Arrive between 6:30 and 7:30 PM for the best light at rooftop bars and before the after-work rush. Avoid weekends and holidays unless you want the full crowd.
Are there any dress codes?
Smart casual is the rule. No flip-flops, shorts, or sportswear. At The Connaught and The Lanesborough, men often wear jackets, though it’s not mandatory. When in doubt, lean toward polished jeans and a button-down. It’s not formal, but it’s not a pub either.
Which bar has the best view in London?
Sky Garden wins for panoramic city views. But if you want something more magical, The Roof Gardens Bar beats it with its living garden, flamingos, and waterfall backdrop. For a classic London skyline with the Thames, The Lanesborough’s view of Hyde Park at dusk is unbeatable.
Next Steps: Where to Go After
After your hotel bar experience, consider a late-night snack. The Connaught’s kitchen stays open until 1 AM with truffle fries and oysters. The Zetter has a tiny kitchen serving duck confit toast. Or just walk-London’s streets are safest and most beautiful after dark. Let the night linger. These bars don’t just end your evening-they elevate it.
