A little bit of beef, pork, liver or pork balls, and a few sprigs of morning glory, are also added to the bowl.
What makes the noodles special is that the bowls are small at about three to five bites, and an average diner can eat many bowls. Tables sometimes compete to see who can stack their empty bowls the highest.

Broth, boiled for hours, is poured over a bit of tender meat with noodles, some light bean sprouts and maybe a little green morning glory, which steam in a boiling caldron before being put into your bowl.

38. Cha Yen
The answer to coffee and tea drinks from around the world is Thailand's very own and very sweet cha yen. We admit, it's not a food, but it's certainly deserving of a spot on our list as it's so damn refreshing.
Though it is called Thai ice tea, the actual tea flavor is somewhat unrecognizable as it is overpowered by a huge portion of sweetened condensed milk and then heavily iced.
