Champagne Bar at 116 Pall Mall

You're walking into something that gets champagne seriously—this isn't about Instagram flutes and overpriced mediocrity. The Champagne Bar at 116 Pall Mall sits on one of London's grandest streets, and it carries itself with genuine expertise rather than pretence. They've clearly thought about what they're pouring, with a list that goes beyond the obvious names. The space itself has that refined-but-not-frosty atmosphere that makes you feel like you belong, whether you're in for a single glass or settling in for an evening. It's the kind of place where the bar staff actually know their stuff and will talk you through what makes each bottle tick.
