ก๋วยเตี๋ยว (guoi dtiao) is one of the most ubiquitous street foods in Thailand and is a kind of noodle soup. It’s probably one of the most customizable Thai dishes out there, from start to finish. You get to choose the noodle size, whether you want broth or not, the kind of broth and the meat. Plus, at the table you can add flavorings to your bowl as you like it.
Guoi dtiao is a dish that is Chinese influenced, as so it is one of the rare things in Thailand that you eat with chopsticks (there’s also an Asian-style spoon for the broth). This dish is pretty strictly eaten at street stands, and so rather than give you a recipe for guoi dtiao, I’ll give you the steps to ordering your own bowl.
