Bar @ 26 Leake Street

You'll find yourself in the thick of Waterloo's graffiti-covered underbelly when you descend into Bar @ 26 Leake Street. The railway arches create this wonderfully raw industrial backdrop—all exposed brick and atmospheric lighting—that feels a million miles from your typical West End cocktail joint. The drinks are genuinely considered, not the Instagram-bait sort, and the bartenders actually know what they're doing. It's the kind of place where locals outnumber tourists, the crowd's unpretentious, and you can have a proper conversation without shouting over a DJ.
