I have been to ChuChai 5 times now. Trust me on this, get the sticky rice and the crispy duck! I would have given them 5 stars but the last time I was there, the food arrived cold and we asked them to reheat it. It came back to the table just as cold the second time.
The patio is a great people-watching spot in the summer plus it's bring your own wine which helps keep the cost down seeing as it is a tad overpriced.
