The Story Behind Connaught Bar, London

There is a silver trolley at the Connaught Bar in Mayfair that has become one of the most photographed objects in the history of cocktail culture. It holds 7 bottles of gin and vodka, 3 vermouths, a small collection of house-made bitters, and a mixing glass set precisely in a bed of ice. When a guest orders a Connaught Martini, the trolley is wheeled tableside. The bartender prepares the drink in front of you, adjusting the ratio according to your preference, finishing with a few drops of whatever bitters the season demands. The whole process takes about four minutes. No bar in the world has made a single four-minute ritual so famous.

The Connaught Bar held the title of world's best bar for three consecutive years, from 2020 to 2022. It sits inside the Connaught Hotel on Carlos Place in Mayfair, a property that has been open since 1897. The bar itself was redesigned by India Mahdavi in 2008. But the story of how it became the best bar in the world belongs to one person: Agostino Perrone.

Agostino Perrone and the Long Game

Perrone grew up in Verbania on Lake Como, the son of a restaurateur. Hospitality was not a career choice so much as the language of his family. He trained in Italy, moved to London in 2000, and spent the early years of his career working in establishments where learning the craft was the primary objective. He arrived at the Connaught in 2008 when the bar underwent its India Mahdavi renovation and was relaunched with a new brief: produce one of the great hotel bars of Europe.

What Perrone built over the next 15 years was not the result of a single inspired decision. It was the compound result of thousands of small decisions, each one made in service of an idea he has described simply as "perfect hospitality." That means the bartender knows your name before you arrive if you have been before. It means the glass temperature is perfect. It means the music is adjusted based on who is in the room. It means no guest ever waits more than 8 minutes for their first drink, regardless of how busy the bar is. These are operational standards, not aesthetic ones. They are far harder to maintain.

By 2016, the Connaught Bar had climbed into the top 10 of the World's 50 Best Bars. By 2018 it was in the top 5. The trajectory was not the result of marketing or media strategy. It was the result of a bar that was consistently getting better at doing what it had always set out to do.

The Connaught Martini

The Connaught Martini is both the bar's most famous drink and one of the most misunderstood ones. It is not a single recipe. It is a conversation. The base spirit (gin or vodka), the vermouth ratio (anywhere from a whisper to 1:5), and the bitters choice change with every guest. The 7 house-made bitters include cardamom, coriander, lavender, lime, grapefruit, tonka, and a seasonal creation that changes quarterly. The tableside preparation is designed not to be theatrical but to involve the guest in a genuine decision about their drink.

Perrone has said he created the trolley format in response to a simple frustration: most guests ordering martinis at a hotel bar had no idea they could have it any way they wanted, because no one ever asked. The trolley is a prompt for that conversation. It says: this is your drink, and we are here to make it exactly right for you. The ritual that followed became famous because it delivered on its promise every time.

India Mahdavi's Design and Why It Works

The physical bar is itself a work of careful calculation. India Mahdavi, the Iranian-French architect and designer known for her work in colour, was briefed to create a space that felt simultaneously intimate and grand, contemporary and rooted in the Connaught's 125-year history. Her solution was a palette of sage green, silver, and off-white, with hand-painted mirrors, bespoke glassware by Salvati, and lighting that shifts in warmth through the evening. No element of the design was resolved quickly. The glassware alone took 14 months to finalise.

The bar counter itself is a single piece of marble, 11 metres long, custom-cut from a quarry in Portugal. The height, the overhang, the footrest below the counter, the spacing of the seats: each dimension was specified by Mahdavi and Perrone together, tested with real staff before fabrication. The result is a working bar that is also a designed object. Bartenders move behind it with the fluency that only comes when the physical environment is built around the work.

London's Position in the Global Bar Scene

The Connaught Bar's repeated success at the world's best bar level reflects something broader about where London's cocktail bar scene sits globally. London has more internationally recognised cocktail bars than any other city in Europe, and its hotel bar culture in particular has no parallel. The Savoy's American Bar, Dukes Bar in St James's, The Fumoir at Claridge's, and the Blue Bar at The Berkeley all operate at a level that few hotels anywhere in the world match.

This is partly historical. London's grand hotels have been serving serious drinks since the late Victorian era, and the traditions of hotel hospitality have been maintained through a culture of long tenures and rigorous staff training. Perrone has been at the Connaught for 17 years. His bar manager Giorgio Bargiani has been there for 12. That institutional knowledge and continuity is not something you can shortcut.

What Makes a Great Hotel Bar

The Connaught Bar's success has reinvigorated debate about what separates a great hotel bar from a great standalone bar. The honest answer is that the two forms are different challenges requiring different solutions. A hotel bar must serve guests who are staying in the building, often jet-lagged or disoriented, alongside local regulars who have come specifically for the bar experience. It must operate comfortably in the daytime as well as at night. It must maintain a standard of dress and behaviour consistent with the hotel's position while remaining genuinely welcoming rather than exclusionary.

Perrone has talked about this distinction in terms of the concept of "the host," which he sees as distinct from the concept of "the bartender." A bartender makes drinks. A host creates an environment in which people feel they belong. At its best, the Connaught Bar achieves both simultaneously. The difference between hotel bars and standalone bars is most legible in a room like this one, where the weight of the building's history is an active ingredient in the experience.

After the Title: What Happens to the World's Former Best Bar

The Connaught Bar moved to the "Best of the Best" category after its third consecutive top ranking, meaning it can no longer be voted onto the World's 50 Best list. This rule was designed to open the rankings to new contenders. For the Connaught Bar, the practical effect has been a slight decrease in external pressure and an increase in freedom. Perrone has described the post-title period as the most creative of his tenure.

The bar continues to evolve. The seasonal bitters programme has expanded. New signature cocktails have been added alongside the classic Connaught Martini. A private dining room adjoining the bar was converted into a second cocktail space for smaller groups. The trolley still rolls out to every table where a martini is ordered. The things that made the bar exceptional have been retained because they are intrinsically right, not because they are required by an award structure. That permanence is probably the most telling sign of genuine quality.

Visiting the Connaught Bar in 2026

Book a table for a weekday evening if you can. The experience at 6.30pm on a Tuesday is quieter and allows more genuine interaction with the staff than a Friday night at 9pm. Order the trolley martini as your first drink regardless of your usual preference. Then follow the bartender's recommendation for the second. The hidden gem bars in London offer different pleasures, but the Connaught Bar is one of those rare rooms where the price of admission is entirely justified by what you receive. If you have only one drink in Mayfair this year, make it here.
