Ton Tann Market is one of Khon Kaen's easiest evening food stops, with stalls, casual restaurants, clothes, music, and the cheerful clutter of a Thai night market. It is more organised than a street corner market but still local enough to be useful.
Come hungry and graze. Grilled meats, som tam, fried snacks, desserts, and cold drinks are the point; the shopping is secondary unless you need a T-shirt or phone case.
