The Johannesburg Sunday Express had a fine time riffing on the many connotations of the heart: the "tender heart, ......, the heart that sends its golden tendrils to the furthest corners of the body and the heart which reputedly houses the dark chambers of the soul."
Does "had a fine time" simply mean that "spend a lot of time"?
What does "golden tendrils" mean?
Fine time means they enjoyed themselves. It probably went on for a while, but pleasure is the key idea. A tendril is a thin thing some plants have to hold onto things, so they would be like little thread or roots connecting the heart to all parts of the body.
