After reading Amy's post (linked below), I went to Hai Au for lunch today with three companions. We arrived around 11:50 AM and were there for an hour, and were the only customers the whole time. We ordered two apps, fried spring rolls and summer rolls. The spring rolls were perfectly cooked and tasted good, but nothing really special. They were served with a nuoc mam-based dipping sauce. The spring rolls were also good but not outstanding; they were accompanied by a hoisin-like sauce with chopped peanuts, which was tasty. We all opted for either pho bo (beef noodle soup) or pho ga (chicken noodle soup) for an entree. It was a huge serving, accompanied by lots of mung bean sprouts, lime wedges, fresh basil, and thin jalapeno slices (one per person). I had the pho bo and the beef was already in the soup and cooked when it was served. There was a huge amount of noodles. It was very good, but IMO My Linh's pho bo still beats it by a pretty good margin - the depth and complexity of the flavors in the broth at My Linh stun me! The service was attentive and friendly and the prices very reasonable. I don't think they have a liquor license yet. My companions were all very happy with the meal.
