You'll find yourself on Handyside Street—that stretch near King's Cross that's genuinely transformed—pushing through the door into something properly grown-up. The interior is pared-back and dark in the best way, all exposed brick and thoughtful lighting that makes you want to linger over something strong. The bartenders here know what they're doing: cocktails are precise and considered rather than showy, and they'll chat you through their current menu without any pretension. It's the sort of place where locals actually come to drink, not just Instagram their way through a night out.
