Phở or pho is a Vietnamese soup consisting of broth, rice noodles, herbs, and meat, sometimes chicken. Pho is a popular
food in Vietnam where it is served in households, street stalls and restaurants countrywide. Pho is considered Vietnam's
national dish.
Pho originated in the early 20th century in northern Vietnam and was popularized throughout the world by refugees after
the Vietnam War. Because Pho's origins are poorly documented there is disagreement over the cultural influences that led
to its development in Vietnam, as well as the etymology of the name. The Hanoi (northern) and Saigon (southern) styles
of Pho differ by noodle width, sweetness of broth, and choice of herbs.
