Facilitating London's love affair with Prosecco, the superior fizz served at Cartizze hails from the very vineyards that give this high-end perch its name. Done out with real panache like a 1930s Lake Como villa, it’s quite a looker – all lilac and cerulean leather, oak panelling, marble, mirrors and metallic sheen. And if you’re dressed in anything less than Armani, you'll feel like a Puglian peasant next to Cartizze's average fashionista. Venetian bubbles form the basis of various fancy Bellinis as well as vodka-laced Sgroppino and an Olive Oil Gin Fizz – although we’re crazy for Mad Max (Monkey 47 gin, orange and chocolate liqueurs, blood orange pressé, banana and spiced sugar) and other Mayfair-priced alternatives such as a mezcal Negroni served from an antique trolley. To eat, expect truffle and Pecorino arancini, San Daniele ham-wrapped figs or scallop, apple and 'nduja sliders.
