Quaglino's
One of the best known restaurants in the city, where even the Queen has dined, Quaglino's is a high-end destination in the West End. Expect gorgeous dark red and gold interiors, with a grand stage covered by elegant velvet curtains, with a cocktail menu that's been in the works since 1929.
They're hosting a masquerade ball for New Year's Eve, with the option to enjoy an early dinner or book a main sitting to attend the party too. Prices start from £150 per person, with dishes including chicken liver parfait, pumpkin and ricotta tortelloni and juniper-smoked Highland venison fillet.
