Two Floors

You'll find yourself on one of London's most touristy streets, but Two Floors actually delivers the goods. The setup is clever—split across two levels with proper bar seating where you can watch the mixologists work, plus tucked-away booths that feel more intimate than you'd expect given the Carnaby postcode. It's the kind of place where they take their spirits seriously but won't make you feel like an idiot if you just want a solid gin and tonic. The crowd tends towards post-work drinks and date nights rather than lager-fuelled stag dos, which tells you something.
