Having never been to Thailand I do not know how authentic the food is, but I do know that the owner chef is from Thailand and also imports authentic ingredients. The food is always of the highest quality and tastes fantastic. Fresh, light and fragrant. You can also request if you want it with more or less chilli. I would recommend this restaurant and am surprised at the negative reviews as the food is great and the price is on a par with others as the price includes rice or noodles and are not charged as extras.
Tau (the owner chef) has recently started cookery lessons\demonstrations and I have attended recently and found it most informative and inspiring. She really is a great chef and knows her stuff.
The small restaurant is an ecclectic mix of decor which only adds to its charm.
I have eaten here many times and hope to return many more times.
