When I was in Omaha, Nebraska visiting a friend, she took me to Beercade. It had my favorite pinball machine, ‘Arabian Nights’. They also had a 3rd Strike machine which got a lot of play from me, Marvel vs Capcom, House of the Dead 2 if I remember right. Pretty cool place.
In northern Colorado somewhere near Boulder I went to a place called Tilt Pinball. No fighting games but many fun pinballs and old old classics like Galaga and Dig Dug. They had a Capcom pinball machine called Pinball Magic which was the highlight for me.
I saw @antillese mention Ground Control in Portland. I went there back in 2013. Played some 3rd Strike and Ninja Turtles. I went there by myself and during afternoon so it was functioning as just an arcade at the time.
Lastly, in my town of Rapid City, South Dakota, we have a pretty cool spot called Press Start in our downtown. It started as just a basement of a bar with it’s own bar and arcade cabinets, but then expanded into the upstairs part too. The upstairs is all kids stuff and ticket games, but the dungeon is where the great stuff is. Sunset Riders, a line of pinballs from old to modern, Killer Queen, MvC, Soul Calibur, Galaga, a Play Choice 10, Donkey Kong, just lots of great stuff.
I bought my first arcade cabinet from the guy who opened this place years before he started it.
It’s a fun place, they used to sell 40’s too, so you could be playing 6 player X-Men sipping on 40’s with the boys.
