If you enjoyed the ones in that arcade you'll really enjoy playing one that's actually playable.
Last time I was there LOTR had no GI (and it's been missing the spinner since it was in Goodge St years ago), there were so many stuck switches on SM I got 100 million without touching the machine and the flippers on Met were so shot you couldn't even make sparky from the right flipper let alone a ramp.
If you're London based head to Chief in Turnham Green or Brewdog in Shepard's Bush where the games are well cared for and it'll be a different world!
