Dear Foodie,
Thank you for your observation that our food is usually great, but on this occasion you found a takeaway steak from a Thai Restaurant to be overcooked. The ancient belief is that cows in the Thai forest were eaten by tigers. People would come across the remains of these cows and they imagined the tigers would have cried because most of them left the brisket cut to rot instead of eating it. People used this cut to cook a delicious dish and named it "crying tiger". So traditionally, brisket was used for the dish,which was well cooked. Thai chefs generally are not trained or experienced in the western manner of cooking steak rare, medium, well done etc and if this is what you like I suggest you avoid this selection. Like you, I prefer medium rare and mostly I find steak houses struggle to get it right these days compared to a few years ago. So I do not hold high expectations of a Thai restaurant in this regard. In my view, the dipping sauce is the critical element of the dish. So I hope you will forgive on this occasion and we may have the privilege of your custom in the future.
