Probably one of the best restaurants I have eaten at - and I have eaten all around Europe. No surprises because one of the owners has probably sampled at 90% of Michelin starred Restaurant in the world. Its not a thai place - its more french influenced gastro pub stuff.
the lamb shoulders and the ice cream sandwich is a must have. A meal for two (with mocktails) cost 2000 baht. Phenomenal value as well.
MUST VISIT (ps. was awarded of the the best restaurants in Thailand for 2013)!!
The only drawback is that its a little hard to find. But I suppose thats what keeps the riff raff and tourists out. The crowd was a mix of thai folks and knowledgable expats.
