About London
City overview
London sits on the River Thames, where Westminster, the City, South Kensington, Camden, Shoreditch, Notting Hill, Greenwich, Mayfair, and Covent Garden compress royal government, finance, museums, markets, theatre, and immigrant food into one transport map. The Tube, Elizabeth Line, National Rail terminals, and river piers make the city work as a set of village-like districts rather than one walkable center.
Food & drink
London food spans fish and chips, full English breakfasts, Sunday roasts, pie and mash, Brick Lane curry houses, salt-beef beigels, jellied eels, and modern pub dining. Borough Market, Brick Lane, Chinatown, Brixton Village, Broadway Market, and Southall are the first food map rather than one single restaurant row.
