This place is not much to look at (and unfortunately, not so clean) and there's ALWAYS a line out the door, but you'd be very hard-pressed to find another Vietnamese restaurant that serves their signature dry noodle bowl. And even if you did, it wouldn't be as delicious as they make it at Nam Vang.
So it's basically a bowl of cooked, thin, rice noodles. It's dry because the broth is served to you in another bowl on the side (in the bowl, you'll even get a chunk of bone with bits of tender pork to nibble - it's the bone that was used to cook the broth with). The noodles come with an assortment of thinly sliced meat and / or seafood like imitation crab or shrimp, bean sprouts, celery leaves, and drenched in a garlic-minced pork-soy sauce concoction. I highly recommend drenching it with lemon or lime as well. When it comes to you, you pour some or all of the broth in (I prefer a little at a time instead of all at once) and slurp. It's amazing. Def one of my favorite Vietnamese dishes. Even more flavorful than pho!
