Food: Though still not as good as food from Little Saigon, this restaurant has the most authentic Vietnamese food I've had in Vegas. They have real broken rice, and it's good. The spring rolls were a bit bland (even with the sauce).
Service: Kinda weird. During the first half of our stay, we were being checked on every 10 minutes. During the latter half, we were kinda getting ignored. But you can't really expect excellent service from places like these.
Ambience: Hole-in-the-wall. Looks a bit messy; but that just makes it look all the more authentic :)
3 stars for average Vietnamese food, +1 star for broken rice.
