DanDan hamburg is a fast food restaurant of Kaohsiung and Tainan. They are like KFC, because they also serve fried chicken. But with some extra Taiwanese food, like mian xian (thin noodle soup).
The noodles are very soft and there is also fish cake in there. You hardly need to chew.
Mos Burger has rice burgers. We had the beef/kimchi and pork version. But it just taste like rice and meat.
