Ton Tan Green Market is a 40-rai, garden themed area built just three years ago in Khon Kaen. Ton Tan Market as it is known in Khon Kaen. Located right in the center of the city, it is easily accessible and if you are in Khon Kaen a visit is almost obligatory. The market attracts huge crowds every evening and it is a great place to pick up trinkets and gifts. It’s a big place to wander around, and you should put away at least a couple of hours to do it. Here you can find really nice restaurants and boutiques.
