We found that place by accident because we had rented a house nearby. Its in a very authentic Thai neighborhood, when we were there it was packed with locals. Surprisingly they had an english menu! You get classical northeastern Thai dishes like "Larb" or "Som Tam" in different variations and in a very high quality. They also offer whole grilled fish. The prices are very reasonable. We paid about 500 baht for a whole menu and drinks. Highly recommended!
