Been coming year for years since I moved to AZ in 2001. I don't know what it is but their Tom Ga Kai soup is to die for. The texture is just perfect and the taste is very delicious, just enough lime and kefir, it is one of my favorites! The place has a nice ambiance, they renovated a few years back and now it looks more spacious. Service is always good and I love the little candies that's available when you exit the restaurant. Parking can be a challenge but so it is with other downtown area restaurants. This is a must try!
