If you speak a little Thai it helps?
I actually love this place, the food is not the cheapest, but they have always given us extra things like deserts. I greet them in Thai and speak some basics and they are very respondent.. (I think it was a respect thing and they have always been great and given a discount.) Great location near the beach. At least try a Thai greeting off of you tube, and by all means bow :-)
