Evans & Peel Detective Agency

You'll walk past the nondescript detective agency storefront on Earl's Court Road and think you've got the wrong address—that's entirely the point. Push through and you're transported into a 1920s noir fantasy, all dim lighting, wood panelling, and the kind of theatricality that makes you feel like you're in on something. The bartenders take their craft seriously without being insufferable, mixing proper cocktails that actually taste like something rather than just looking Instagram-friendly. It's intimate without feeling cramped, and the whole experience taps into that particular London joy of discovering something properly atmospheric tucked away in SW5.
