Maximizing enjoyment of family meals

How can we get the most out of our family dinner times? Our family recently committed to sharing mealtimes together at least three times a week. It was an adjustment in the beginning. There were a lot of rough spots, but I'm pleased to say that we're already seeing some positive results. At this point my major goal is to be intentional about making mealtimes meaningful. In particular, I want to find ways to make the very best use of the time we spend together. Do you have any suggestions for things we should be looking to accomplish as we gather at the table?
