Im studying in Korea and one of the best things to do with a small group of freinds is visit a multi room. Its a room where you use a Giant TV to an play computer games, nintendo wii games, watch movies, or sing some karoke all in the one place!
But the one thing that takes you by surprise in Korea is how beautiful they make some of these places. Internet cafes desks look like works of art. This hallway for example is just at a multiroom. A bit snazzy to do some karoke or play nintendo.
