I live nine years in Taipei and went to Holiday KTV for only 5 times. I love singing but the songs do not like me at all that's why I only end up listening to friends :) Kidding aside, Holiday KTV is the only KTV I ever visited.
Danshui is one of the most famous places in Taipei in terms of Night Market. It's not only near the river bank and opposite of Bali (another town), but also it has its own history.
