The Cosmopolitan is a classic cocktail that gained popularity in the 1990s and has remained a favorite in London's cocktail bars. Made with vodka, cranberry juice, lime juice, and triple sec, it is a sweet and tangy drink that is often garnished with a twist of orange peel. Many bars in London offer their own variations of the Cosmopolitan, using different types of vodka or adding unique flavors like pomegranate or elderflower. Whether you're a fan of Sex and the City or simply enjoy a fruity and refreshing cocktail, the Cosmopolitan is a great choice.
