British food has transformed dramatically in recent decades. London is now one of the world's great dining cities with extraordinary diversity. The classic full English breakfast (eggs, bacon, sausages, beans, tomato, toast) is a cultural institution worth trying once.
Fish and chips by the seaside, Cornish pasties, Welsh rarebit, haggis in Scotland, and afternoon tea (sandwiches, scones, clotted cream, jam) are authentic regional experiences. The UK's Indian restaurant culture (chicken tikka masala is practically the national dish) reflects its multicultural heritage.
