In London you can do Afternoon tea and my Tuesday outfit is definetly inspired by "tea time".
Best places for Afteroon Tea?
The Wolseley in Piccadilly is just delicious in gorgeous surroundings where you can sit and watch. They have scones with fresh clotted cream and jam, sandwiches and delicious little pastries and tasty tea -of course, from all over the world.
Aubaine in South Kensigton, little cute-ish french patisserie, breakfast, lunch tea or just coffee, they have delicious brioche and freshly made croissants, and yummy croque monsieur et madame, just perfect! Fantastic fro some pre or post shopping!
Fortnum & Mason, A classic! One of the best food halls and having been around for more than 3 centuries expectations are high. This is also THE place to buy tea.
The Orangery at Kensigton Palace, definitely the best scenery in town. Al fresco seating with green surroundings in the middle of the royal park. Very popular for all the good reasons.
