Our little family went on a weekend getaway to Zagreb during Advent in December. We did the Illusions of Torture walking tour with our guide Nina. Since we have 2 kids, she suggested that maybe the Torture Museum was not the best idea. I respect that she took that into consideration and instead we went to Nikola Tesla Technical Musem. The tour was very interesting, so fun and would recommend to families with kids. We got the info about this tour from tourist office at the main square.
