This was at the top of a Lotte Mart, I swear...but the address is saying "Home Plus" so I'm confused. Maybe the wires in my brain are getting mixed up. At any rate, it was right next to a food court. It was a more calm play space, and though kids of many ages could be there, I'd say it was best for kids age 3 and up (American age 3). My son liked it because the middle space had a train table and a place to play with a car ramp. He also enjoyed trying out a few of the activities you could take off a shelf. My understanding is that these are all over Korea, but I have yet to find another one. Name in Korean is "블럭버스 전주교육원." I recommend having someone call the listed number to verify the location since I could swear it wasn't at a Home Plus...
