My wife and I have been there five times as of Dec 2013. We really love the food! Possibly the best Thai in Penrith (even with some great competition).
Pros - Great and consistent food with generous helpings, fast service.
Cons - Basic furniture (but I don't really care about this), Price (It seems a little expensive to me, but I think all Thai food is expensive. You pay for what you get, which in this case is REALLY good food.)
Summary/TL:DR - A great restaurant, we prefer it over all other Thai restaurants in the Penrith Area. The food quality and consistency overpower the slight negatives. Love it!
