Klub4Kidz Birthday Parties

Youngsters spend an hour in this Brooklyn space’s four-level indoor playground. After tearing through slides, tunnels, web bridges and crawl tubes, they’ll enjoy pizza and juice in the party room. The basic package also buys invitations, paper goods, music and dancing. Add-ons include cake, entertainment or additional activities like rock climbing, hair braiding and candy sushi-making. DIY mavens can also rent the private room ($395 for three hours) and create a custom party. Ages 3 and up.
