About I/O Arcade Bar

I/O Arcade Bar is Madison, WI’s place for drinkers with a gaming problem. Located in a refurbished warehouse, this arcade bar bills itself as a place for “nerds of all kinds” with an 80's vibe reminiscent of Aladdin's Castle at the mall. I/O has a large selection of video and pinball games, including Deadpool and Godzilla Premium, all run on quarters, or choose from a library of board games. I/O is a 21+ venue but hosts all-ages hours every Sunday from 11 am to 1 pm.
