"These famous green huts with kitchens were founded in the 19th century by The Cabmen’s Shelter Fund, as pit stops for black cab drivers in need of a cup of tea and fried breakfast. Now only 13 of 61 original huts remain, with 10 open for business. Only cabbies are allowed to take a seat inside, but they’ll serve anyone through the hatch. The sandwich is a basic arrangement of bacon, sliced white, butter and sauce, which hits the spot as only a no-nonsense breakfast sandwich can." - Helen Graves
