Humble it may look like, but dive in! The Esan food is worth it. This is not "diluted-for-tourists-Thai". Several lunches and dinners here and not one disappointing dish. Spicy papaya salad here had the rare balance of chili, lime, etc and crisp papaya to make it most refreshing. The stir-frys were all good. The coal-BBQ'd catfish was the winner though. Friendly, and fast (as in telling me that "this time catfish not ready, takes 30 minutes" - I took a stroll...and came back for when the fish was done and rested.
