I very fondly remember a McDonald's Playland restaurant near my house in Stratford, Connecticut. This wasn't just a tube and ballpit playground; the McDonald's Playland had a complete underground floor full of rides and playground equipment themed after Ronald and his friends. I think they're all gone now, but I found a great article about some of those old attractions here. I vividly remember a kid getting his head stuck between the bars of the Officer Big Mac Climber. Talk about taking a bite out of crime!
