Need kind explanation! I spend about an hour but still not so sure about the payment....

Are there room charges in KTV?

I have only been to a korean KTV for buyer entertainment...and shit...they charge room, girl charge, and even service tax is 3 digit....

but here I see post like:

chivas $XXX
Girls tip $XX
Mama san tip $XX

So If I go with my buddy and get 2 girls and get a chivas and spend 2-3 hours singing and drinking, how much it will cost? I heard it varies depending on the on the extra service and the level of the KTV...so assuming something llike Kabuki level...how much it will cost without extra service?

Don't flame me, I tried to find it on my own but just too many posts..
