The first curry restaurant in the UK opened in 1809.
(Yes, over 200 years ago, an Indian migrant, Dean Mahomed, opened Britain's first curry house to cater to the fashion for spicy food. The restaurant was called the Hindostanee Coffee House, and customers could smoke hookah pipes and recline on bamboo-cane sofas as they tucked into spicy meat and vegetable dishes. Nowadays they are more likely to be swigging pints of lager, and falling off their chairs.)
