Hi hquity, thanks for the reply.
I'd like to think we know Thai food reasonably well. I myself have been to the country probably 5 times in the last 6 or 7 years (Bangkok, Chiang Mai, Mae Hong Son, Koh Samui). Both myself and my wife are of Asian descent and can handle a fair amount of heat before reaching for the ice cold drinks...
I like to find Thai restaurants/eateries which offer dishes/foods that either I have not seen before or are specific to the region where we are eating. I'm not really interested in eating another green or red curry or a pad thai... Dishes I like are the unusual soups (ie, not the straight Tom Yam, Tom Kha varieties) and also the salads (especially the Northern/Isaan types)...
We haven't booked our hotel yet but we have been told to avoid Patong as it's too developed. The areas we have been recommended to stay are Kata, Laguna or Mai Khao areas.
As for budget we are not really restricted... But based on experience it's not usually the expensive places where you have those meals that you remember... Normally you experience those in some off the road but well know by the locals place which serves amazing food at very reasonable low-mid prices...
I hope that gives you a bit more information to go on :-)
Thanks again
