I have been a customer for many years and i have tried other thai restaurants (grudgingly) and no other restaurant compares to this. The food is amazingly delicious, i have tried nearly every dish on the menu and i was blown away by the flavours EVERY time.
I highly recommend the Pork spare ribs, and the home made Tom Yum soup.
Also one of my favourites, the duck salad,"Yum pet"
The owners are a married couple and the wife has 20 years experience in thai cooking. The husband is a lovely man who answers the phone and will take the time to ask how your day has been even if he is flat out busy. If you are not a local, i have heard their daughter who was trained by her mother has a restaurant of her own in the northern suburbs, "Silk Thai Restaurant " and i have heard great reviews of that restaurant too.
Overall, I have to say this is my favourite Thai restaurant out of Thailand. If you want true thai food, come here.

Approximate cost: $16
