As sophisticated dining experiences go, afternoon tea is one of the most refined. Head into the fashionable surrounds of Euston and find Savannah, an eco-friendly eating spot which is part of the esteemed Sustainable Restaurant Association. Tea starts with a selection of freshly made sandwiches which include salmon and horseradish, salted beef with mustard, and egg and cress. Then it's time to satisfy that sweet tooth with macaroons, flavoursome Battenberg cake, and homemade scones which come with fresh clotted cream and organic jam. As well as a variety of speciality teas and coffee, you'll also be served a refreshing glass of Champagne each. This is the perfect way to grab your own slice of decadence
