[Nyororin]

Back prior to having a kid, we used to hang out in them a lot. They usually have plans where you can stay there from 8pm until the next morning, with dinner, breakfast, and drinks included for something like 1200yen.

Borrow a little room with a big tv, all the game hardware, a PC, etc - and sit in there trying out tons of games, browsing the web, reading manga, etc.
