One of my all time favorite Thai boat noodle places was right down the street from where I used to live in Bangkok on Soi 31 called "Noodern". I hope it's still there with that incredibly satisfying "Guay Tiew".
It's the heft in boudin noir, the intrigue in jugged hare. It's a silken presence in soups and congee. Blood is bold, a bit bitter—and, frankly, kind of creepy. But we like it—especially in this spicy, delicious Thai noodle soup.
