Chai Kueh is a very popular street snack in Pontianak (Khun Dian), West Kalimantan Indonesia. You can buy it from 'toko kueh' or snack shop near the wet market. But the most interesting is the Chai Kueh still available via street seller who distribute the snack door to door in city area. Per piece is about Rp.500 to Rp.1000, that is about 10 to 20 Singapore cents only!!!
