"This genius business bills itself as a "playspace and retreat." It's outfitted with a full, modern, and blessedly clean kids playspace that's supervised during open hours. While kids are playing, parents can drink tea and coffee in a parents-only room, plug in and handle emails in a workspace, or, best of all, sign up for massage and reiki treatments. While the concept works best during the week, this is also an excellent place to host a weekend birthday party."
