We don't actually eat "Pad Thai" as our national dish.

Although "Pad Thai" has been promoted to become a cultural ambassador worldwide, for Thai people, it is considered a special meal that is eaten only occasionally, or perhaps as a dinner option at a night market. If you ask what the true "national dish" is in the hearts of Thai people, it would be "Pad Krapow Gai with a Fried Egg"—a dish found on every street corner, from humble roadside shacks to food courts in luxury malls. The fiery heat of holy basil stir-fried with chili and garlic, releasing an aroma that carries for blocks, is the taste that Thai people crave most in their daily lives, rather than the sweet and sour flavor of Pad Thai that foreigners are accustomed to.
