Kim Yong Market is famous for the locals to get imported snacks from Malaysia and Singapore. You will find many muslim vendors sellling merchandise on the street. The market itself has many small stalls nestled on narrow alleyways. It is covered and can get a bit clasterphobic sometimes.
What to buy: According to my Thai friends, one of the most popular souvenir from Hatyai is Pringles potato chips! Apparently, they are imported from Malaysia and are cheaper than in the rest of Thailand. Other things to be considered at this market are local fruits, all sorts of nuts, and anything Thai!! Batik is also popular at this market.
