|Kow Lao Yen Ta Fo|
|Sen Mee Yen Ta Fo|
Few Yen Ta Fo shops will add chili to the soup by default but 90% of the places won't. The taste for this dish is often sweet and sour which is quite different from other kinds of noodle soup. I know sweet soup is weird for most people but putting sugar in the noodle soup is quite a common practice for Thais.
