Looks like you are on a tour. The food is Tainan and Kaohshiung is pretty good. It is closer to the type of food you find in Malaysia amongst the Hokkien people. Same with the Taiwanese spoken in the South. ShiMenDing is a place where most of the youth in Taipei hang out after school. There are a number of watch shops there, but you really need to know what you want. The place not to miss, in terms of food is the Modern Toilet Restaurant where the food is served in a toilet bowl and the drinks in a urinal. The food not bad, but points for novelty.
