There used to be an arcade at the mall where I grew up...that was probably the last time I was at an arcade. I can now revisit it, a bit, as I just got the Wii version of Rampage: Total Destruction for it's TOTAL mindlessness and nostalgia value (and it was dirt cheap), and it includes the arcade version of Rampage.
I also remember a Pac-man arcade machine at a restaurant back home, too.
