Scales Cocktail Bar

You descend into Duke Street and find yourself in a proper cocktail bar—the kind where they're not mucking about with gimmicks. The space is polished but unpretentious, all dark wood and mood lighting, the sort of place where regulars drift in after work and settle in for the evening. The drinks list is substantial without being exhausting, and the bartenders will take you seriously whether you're ordering a textbook Negroni or asking them to build something bespoke. It's Mayfair, so expect to pay London prices, but you're paying for competence and care rather than just postcode premium.
