Mine had a very nice thai restaurant in a little country community called Na Kae (around 3000people) in Isaan between Nakhon Phanom and Sakon Nakhon. Covid, the war and the deteriorate financial conditions of the locals killed it. My advice is don't, the locals in rural areas cannot afford it. Unless you move to the big cities but with other challenges and don't forget the regio still remains very poor.
