PC bang

Internet cafes, known as PC Bangs, are a common occurence throughout the
average South Korean city landscape. They're similar to British and American
internet cafˇs, but most cater more to online game playing for the younger
generation of Koreans. On average, use of a PC Bang is priced at around
1,000 Won per hour (about 80 cents USD).

In Korean, "Bang" means room, so the term literally means a room or
place for a PC. The meaning room is not exact.
