Duke of Wellington

You're walking down Eaton Terrace and suddenly you've stepped into the kind of pub that makes you wonder if you've stumbled into someone's private members' club—except it's decidedly public. The Duke of Wellington sits pretty in one of Belgravia's most expensive postcodes, but it doesn't do that annoying 'upmarket pub' routine where everything costs £18. Instead, it's got that lived-in, mahogany-dark elegance of somewhere that's been doing this for decades without needing to shout about it. The crowd is proper mixed—locals who've been coming here since they could legally order a pint, the occasional Belgravia resident popping in for something stronger than prosecco, and people who've heard the cocktails are genuinely worth the trek to SW1W.
