I agree about Viet Huong. I've been there on several occasions and had the spring rolls and the Pho and really enjoyed it.
This weekend we tried the Special Hue Spicy Soup and the Caramel Jumbo Shrimp with Rice. They were both great, especially the Shrimp. Only the shredded pork rolls disappointed us, but that was probably because we didn't really know what they were and were surprised that they were served cold.
