Portion size was a bit small for me, made worse by the fact the food itself was so good I didn't want to stop eating.
The service was impeccable. I was eating alone and was seated next to another lady also eating alone rather than the large group of friends which made me feel less conspicous.
This was the best Thai meal I can remember having.
There was very little in the way of atmosphere but it was relatively early on a Fridy night, it may well have picked up later!
