What noodle dish consisting of a clear broth, flat rice noodles, herbs, and meat is considered the national dish of Vietnam?

Pho

Originating in northern Vietnam in the late 19th century, Pho was influenced by both Chinese rice noodles and French meat-eating habits. The name is widely believed to be derived from the French word 'feu' (fire), referring to the pot-au-feu method of slow-cooking the beef broth.
