Milroy's of Soho

You'll find Milroy's squeezed into a narrow sliver of 3 Greek Street, in that particular pocket of Soho where the tourist chaos hasn't quite reached. Walk in and you're hit with the smell of oak and old books—the walls are basically a vertical library of spirits, floor to ceiling, with bottles crammed into every available inch. There's no pretension here despite the serious collection; the bartenders pour with confidence but chat like they're mates, whether you're ordering a £20 whisky or asking what the hell you should actually drink. It's the kind of place where regulars prop themselves at the bar for hours, and newcomers somehow feel immediately at home.
