Though I'm not for expelling children from decidedly mature European playgrounds, I am in favor of kid-free dining. What is one family's easily ignorable background chatter (ie: kids being kids) is another's theater of the absurd.
I'm a big believer in the family meal, in sitting down at the table and breaking bread together. I ate in front of the TV growing up and look how I turned out. I want my kids to have a better upbringing. Or at least a better sense of the place of family and food.
