Just as all the food I eat, nutritious, and tasty. Kau Man Gai, Kau Ka Mu, Krapow, Satay, Kau Phat, various noodle dishes. I simply go in read the menu "in Thai", ask a few questions and order if I am happy. Cheap, fresh, and fast. But as I said avoid anything Isaan other than the barbecue. My guess is you have gotten ill eating what I do not.
