Adult PC bangs, otherwise known as:

인터넷휴게실 (internet hyu-geh-shil), 전화방 (jeon-hwa-bang) or 성인PC방 (seong-in PC bang).

This is a business that has private PC rooms for one person, complete with computer, phone, and sometimes a small bed or recliner. These are places that offer exclusive privacy for phone sex or watching porn videos that have been pre-downloaded from the internet. The clothes hanger, mini-bed or recliner, and token roll of toilet paper next to the monitor, gives the obvious hint of what usually transpires in this environment.

They have varying rates, but if you are strictly going to be using your room for watching porn, then you can expect to pay around 6-7000 won/hour. For phone sex, the cost is a little higher. The customer usually pays by the hour, enters the room and waits for the phone to ring. A woman calls and they chat and there is always the possibility of meeting the woman later. One statistic from a Donga Ilbo report cited that 57% of the contacts have sex within four hours.
