London is so huge that giving you any recommendations can be quite overwhelming, unless you'll find yourself around the St. Katharine Docks (close to the Tower of London). Than I have one for you, this amazing coffee shop that you can't miss! Whenever I'm in London I love coming to White Mulberries and a coffee on the sunny terrace is just what makes my day. They have rather large selection of cakes and savory so you can bite on something yummy while enjoying your flat white (or any kind of coffee you prefer). Can't wait to visit again! xx
