This place is ridiculously good and one of my favorite restaurants of all time. It's unfortunate that I won't often get to eat here anymore, as I'm no longer in the area.
All of their noodle dishes are amazing, and I really like their house special beef hue soup. The spiciness that they prepare their dishes with really adds flavor, and it's not just "spiciness for the sake of spiciness" -- it really enhances everything. That comes hand-in-hand with a warning though: the spiciness levels are far hotter than what you'd see in an Americanized place; a "medium" here might be off-the-scale spiciness at a more tame place. If you're adventurous, you can ask them to go off-the-scale here too ("extra" or "dragon" hot), but I only recommend this if you're very seasoned to spiciness. Just the normal "hot" satisfies this happy customer, who normally orders "15" on a scale of "10."
Bonus: their spring rolls are also prepared very well, with excellent crisp and stuffing.
If I'm ever in the Cleveland area, I plan to take a special trip to this place.
