Now, like many people, I don't normally drink much beverage during my pho meal for obvious reason. The broth in pho is so delicious and can fill you up fast, and your stomach can only hold so much food and liquid right? Why fill your stomach with anything other than the goodness of pho while eating pho?
Here's another poll showing what I mean. The majority of people actually finish their pho to the last drop. Together, "Most of the times", "Often" and "About half the times" combine to 64% of the times that people empty their bowls. I'm definitely in the minority here.
If you really think about it, pho it not like any other food. It really does not need to have certain refreshment to pair with it, or "help" bring out better taste. Pho is good as it is and on its own. It's a perfect Viet street food.
For many people, a glass of water to help wash it all down is all they need while eating pho. And that's what the poll shows.
Interestingly, tea, Viet coffee and beer are the next 3 popular beverages for pho diners. Cold beer even beats Viet coffee by a little bit!
