The Rooftop

You're up here watching the city unfold from above Knightsbridge, which honestly changes how a drink tastes. The Rooftop does that thing where it feels like a secret even though it's tucked into one of London's busiest corners—staff actually know what they're doing behind the bar, and they're not trying too hard about it. It's the kind of place where you'll end up staying longer than planned because the view keeps you anchored, and the drinks justify another round. Whether you're catching sunset over the park or the city lights kicking in, it lands somewhere between proper cocktail bar and civilised hangout.
