This is a great museum that had a lot in common with the Minnesota Children's Museum. Similar play spaces, just that here, it had a Korean touch to it. And, we were among 99% Korean families and saw one white family whereas often it was reversed in Minnesota. Our son had a great time. It's only approximately $4 for each person over 36 months to get in. We asked about annual membership for our family, and it was only about $40, so we signed up for it. So awesome! This place is in the Seoul Children's Grand Park, which looks like a fun place when it's not super cold like it is now. The museum of course it 90% indoors, so great for winter. It looked like in the summer there are some places kids can enjoy, too.
To get there, find your way to line 7 on the Seoul metro and get out at Exit 1.
