Why would parents bring young children to a restaurant where the average price for a complete meal is over $50 per person? Get a babysitter. And certainly, don't let your children run around the restaurant screaming and doing a clog dance on the wooden stairs while you sit at your table yelling "Artemis, come here...Artemis, stop that...girls, behave." Why should my celebratory dinner be ruined because of parents who can't control their kids? And it's just teaching them that they can act however they want wherever they want.
My dog behaves better than that, and he's much cuter.
