Visited twice with family, for lunch and dinner. Authentic, good quality, tasty and delicious thai food prepared by thai chefs. Red and green curries, tom yum, pad thai, prawn/fish cakes were good. Service was ok. Good place to satisfy craving for delicious authentic thai food.

I stayed in downtown for 6 nights and ate here 3 times such fresh and tasty food. Service was great and I would recommend anyone to eat here. The duck and brown rice was just delicious.

We've eaten here a couple of times and the food is excellent. You get a lot of food for the price. The service is good as well.
