Taking tea has been a London tradition for more than 150 years. The practice was launched by the Duchess of Bed ford in 1830 when she ordered a little something to ward off pangs between lunch and dinner. By the 1840s, wafer thin slices of bread spread with chopped cucumber along with light sponge cakes and freshly brewed pots of tea were being served up with tidbits of gossip all over London.
