As you can guess from the geography, it's heavy on the freshwater fish and pork. Also, the heat quotient in true Thai style is very high.
The first dish is your traditional papaya salad but it has pickled crab in it. (If you squint, you can see the bluish crab sticking out on the right hand side.) The crab is intense! It has the consistency of jelly but it's like a concentrated sea-flavor which has absorbed the sweet-sour-salty dressing. Also, featured as a topping is fried crispy pig skin.
The second dish is fried catfish. The fish is cut into thin rounds, and fried in such a way that you can eat it bones and all. Quite delicious!
