Totally recommend but maybe not for tourists
It is a streetside food vendor thus I can't rate it in the same scale with other bistros or restaurants. It is located on a small serene street near downtown Danang, thus there is very little dust. It might be a little problem during summer when the air is hot and humid. The service is quick and the price is pretty decent.
The mi Quang is delicious with a large portion and tasty broth. I ordered one with chicken. There is enough meat in one bowl and plenty of veggie on the side. Totally recommend but maybe not for tourists.
