The Athenaeum Hotel in Mayfair does a couple of tea menus, most notably a savoury tea which includes cheddar scones and chorizo jam. There’s a lot to like here: the elegant setting, the option to add a glass of champagne, and the good value. They do a ‘normal’ afternoon tea as well, but the savoury one is definitely one to keep in mind if you’re with someone who claims they don’t get down with sugar—just know that you need to request this 48 hours in advance.
