This is one of my most favorite Thai restaurants in Sydney and that is saying something - I lived in Thailand. The food is great, authentic and the staff really know what they are talking about. You can even buy authentic Thai snacks like pigs skin at the counter.
If you like your Thai food then this is the place for you. There is always a line in the city one but if you can get out to Randwick this one tends to be quieter. There are many Thais that visit the one in the city so you know you have a good restaurant.
Get there early to avoid the lines
