MADISON’S place for drinkers with a
gaming problem.


Cold beers, great cocktails, and a huge selection of video and board games. I/O is Madison's newest entertainment venue. 

I/O (pronounced I O) is an open and inclusive space for drinkers with a gaming problem.

Try any of our custom cocktails or craft beers and stake out your cabinet - with over 50 games to choose from, you can set a new high score on your own or duke it out with friends. And if the screens get too bright, settle down at the bar or grab a board game and claim a table. There's always something to do at I/O.

I/O is a 21+ establishment. We happily host all-ages times every Sunday from 11am-1pm!
