Ai yoo....taiwan is so expensive leh...I been staying in taiwan for 3 years and I hate it all. Just can't wait to go back SG and can visit Batam and Thailand nearby for weekends.
At lest NT3-5K for 'can tahan' type....NT1K also got but for hardcore type who like 40-50+yr old range type lah...
As for KTV with extra nude dance, play game type be ready to spend NT12k per person for 2 hours. Fucking ex lah.
From my personal experience, I only get ONS a few times over the years. Not easy.
Good luck hunting!
PS: most of the WL are from China
