Can't say this place is the best but it's very decent. They have many different soups such as bun bo hue or bun rieu and they're pretty good. Their grilled chicken vermicelli and their spring rolls are very tasty, but the portion is a bit small. For the dessert, I took their 3 colored desserts. I wouldn't recommend it. It doesn't have that sweet coconut and beans taste I was expecting.
As for the service, it's very quick and they also serve tea instead of water which is a plus.
