On the spiciness meter how hot is this dish? If it's relatively mild (Meaning a wimp like me can eat it without gong into shock.) and the local Thai restaurant serves it, I might order it the next time I go there.
It's relatively mild at it's core. It's basically ramen. The spicy flavors come in by request and desire.
But even the spiciest isn't so bad. You have to take into account that this is basically ramen. I've had the "spiciest ramen" and it wasn't so bad.

The first paragraph alone is a good read, if you're interested in Vietnamese food. The point is basically that the overall style of Vietnamese is reliant on herbs, fish, and soy sauce types of flavors.
You could even do a shrimp version of Pho.

And for anyone that wants to go all out, this is beef, pork, shrimp and vegetables. Everything pho:
If you do shrimp though, I emplore that you try to find botan ebi, or Botan Shrimp. This is referred to as amaebi at most sushi places, "sweet shrimp".
Not just because of the taste, but this is my favorite type of shrimp. It's delicious and light but at the same time holds bursts of flavour.
