When you learn new language what is the first thing you wanna know (apart from say Hi and How are you?)? For me I would say vocabulary about FOOD!
Because one of purposes we learn new language is to communicate and talking about food or eat is the must in our daily life.
Here is what I found in free copy or free magazine about Thailand, published specially for Korean readers. On the top is a list of Thai favourite fruit for Korean. So they could use to communicate and buy fruit they want. At the bottom of the picture is the list of Traditional Korean food that Thai people might want to try or find when they travel to Korea.
I think eating is one of human survivng skill and I am interested in tasting food too. That is why I always try to speak or look at food vocabulary before others.
