The Orangery at Kensington Palace
For an entirely plant-based afternoon tea menu, make your way to luxurious destination The Orangery at Kensington Palace. This historic venue began as a greenhouse in 1704, and today it boasts a vibrant restaurant and charming outdoor terrace, where you can sip unlimited tea and snack on the likes of coronation chickpea wraps, pickled carrot and hummus bagels as well as lemon tarts, all for just £55 each. And if you fancy something a little boozier? You can add on Pimm's or sparkling wine too.
