Not everybody can walk for hours. so if you get tired of walking around in Central Plaza KhonKaen and want to sit down for a while and maybe have something to drink or eat, i suggest Starbucks. And it's also a nice place to meet up with friends to talk or even to do homework or groupwork too! I mean, what's better than doing homework/groupwork with your friends and have unlimited access to food and drink (as long as you have money though hahaha)
