I found by chance like 10 years ago or so Taiko No Tatsujin arcade in a little luna park. It was a really rare event to find it. This is one of my favourite rhythm games.
I once went to one of the large Sega arcades in Akihabara years ago when I visited a friend in Japan. It was wild seeing the people play the rhythm games so well. I could barely follow their movements and they were getting perfect scores on every hit

There was DDR, the drum game in the video, a tapping circle game, etc.
I didn't play much of those, but I did spent a lot of time by the claw machines and ended up winning a stuffed Snorlax and Asuna (from SAO) figurine
Here in the US, we don't have as many arcades as we used to, since the malls that typically had them have died off since the 90s, but there is a growing trend of Bar-cades (A bar and arcade in one) that are smaller sized but still a lot of fun. They usually have games like pinballs, skee-ball, arcade cabinets, etc.
There's a handful of arcades/barcades within an hour of me that I like to go to. My favorite arcade
game is Skee-ball and I even joined a competitive league for it! My favorite arcade
cabinet is Galaga.
Lastly, the biggest arcade in the United States is in my home state

Many arcade records have been broken and recorded there. I loved going there as a kid, so I returned there last year with some friends during a summer holiday which was neat. The four player TMNT game and air hockey took up most of our tokens!
What's everyone else's favorite arcade game?
