The Ram arcade just had its grand opening --- August 2021. It's in Haddonfield, New Jersey, next to Cherry Hill, NJ and about a 10 minute drive from downtown Philadelphia.
I haven't yet visited. However, I'm glad to see a new arcade in my former hometown, literally around the corner from my former residence, and one town over from my current residence.
Based on the arcade's Facebook page, Billy Mitchell attended the grand opening. If you've been there, post your impressions.
