All Bar One New Oxford Street

You're walking out of the British Museum, slightly overwhelmed by marble and tourists, when All Bar One appears like a proper grown-up answer to your thirst. This isn't some Instagram-bait cocktail joint—it's a proper wine bar that takes itself seriously without being insufferable about it. The vibe is polished but unpretentious: you can roll in after work in your office clothes and feel instantly comfortable, whether you're ordering a glass of something interesting or settling in with a bottle. Staff actually know what they're talking about, and the wine selection punches well above what you'd expect in this touristy corner of Bloomsbury.
