Primo Bar, London

You're stepping into somewhere that takes its cocktails properly seriously—the kind of place where your bartender actually knows what they're doing rather than just muddling about. Primo sits right on Westminster Bridge Road, which means you've got the Thames and all its moody South Bank charm practically on your doorstep. The space itself feels grown-up without being stuffy; think proper craft cocktails, not novelty nonsense in test tubes. It's the sort of bar where locals actually want to drink, which tells you something.
