This will sound like an AstroTurf but it's not! Just took myself and the kids to "Arcade club" in Bury (but they have other locations. It's a pay on the door but then free play retro arcade. The Bury site had 3 floors of machines spanning from Asteroid and pacman up to 90s classics like Time Crisis 2 and a few newer machines to boot. Not sure how many machines but easily in the hundreds. All seemed in reasonable condition and nearly all worked. Great way to spend a day and the food was reasonable priced to boot (but not gourmet). Figured some other bit-techers would enjoy and if you have no kids they even do adult only nights. As stumbled over this thought I would spread the word. https://www.arcadeclub.co.uk/
I go to the Bury one for Adults only every few months, get a little drunk playing games until they kick me and my mate out, place is amazing!
