We love Rainbow Library!
My kids and I came every Tuesday at 4 for Lego club (sometimes its a different event) and we also came for rock the library which is one Sunday a month. Miss Jen and the Steam staff are all very patient and amazing with the kids who attend. They occasionally post photos of the things kids have built in the children's library and my son beams with pride when he sees his creations up there. I wish there were more programs/classes but I am happy with what they have so far!
