I cannot vouch for this.
The Greatest Beef Noodle Soup? The Warming, Soulful, Flavorful, Mouth-Watering Beef Noodle Soup of Central Vietnam - Ngu Binh [Thoughts + Pics]
I guess I know where I’m eating next, great writeup!
Pigs bloods is very much an acquired taste. It helps if you take most of it out, but leave one or two cubes and tear them into smaller pieces and dispersed throughout the soup, rather than eating it like a meatball. After a year, you’ll want more. And yes, bun bo is indeed the greatest beef noodle soup and Ngu Binh has the best version I’ve ever had.
