I/O Arcade Bar - Video arcade in Madison - 924 Williamson St, USA

Overall good place to meet friends, have some drinks, and play some games. Good variety of old and new games. Fun atmosphere; I would categorize it mor targeted to the adult crowns vs some retro arcades which are geared towards kids and adults. I would say the cost per game is high (4 x quarters to play 1 game of pinball) so it’s not necessarily a place you would spend a lot of time in given other retro arcades are either free games with drink purchases or a set cost to play all games unlimited.

We had a lot of fun here! Arcade bars are an absolute must-visit on any of our trips and this one did not disappoint. It's in an easy to get to area of Madison and there was plenty of parking around. That happy hour is worth a stop for locals or out of town guests. Any place that has skee ball is going to be 5 stars for us and posting sing along lyrics to make sure hand washing lasts long enough is genius. Thank you for the cool vibe and fun stop. We will be back next time we are in town!

First time at their new location and had a great time! Was a bit disappointed they no longer have Alt beer which is gluten free beer. They only have seltzers and ciders, which is not the same. I'd give them the full five stars if they still had a GF BEER option. Probably won't go back because they don't have that anymore.

The arcade has a ton of games and a solid beer selection. The games use quarters which is better than tokens. The place was easy to navigate as it was a Saturday afternoon. I imagine it would be much busier at night. Played the Simpsons arcade game and some ski ball and some pinball. It has punchout, NBA jam, a s some other retro games. It is nice that it is adults only.

I've been to many barcades and play Pinball in a weekly tournament. I've never seen such a great collection of games in that good of working order ever. Every pinball was working, every'80s and '90s classic had a good monitor working buttons. Very impressed very fun

Fun place to visit. Good variety of pinball, arcade games and drinks! They have skeeball and guitar hero!

I don't really indulge much in arcade games so really couldn't judge on what games were available. There seemed to be a huge variety though. I mostly went to play skeeball, which they have 4 but 2 were broken. They're kinda crammed in the corner so not much wind up space. They weren't true skeeball machines either so a little different set up. The drinks on the menu were cool sounding, and I had 1 of them that was pretty good. I had a really great old fashioned as well and they have great beers on tap.

Easily my favorite hangout spot in Madison. I cannot tell you how many hours I've spent here on the pinball machines. Very clean place with friendly bar staff and good drinks. Check out the happy hours on weekdays and bring some quarters (though if you don't there's an ATM and change machine).
