I guess I disagree that children should be banned from nice restaurants in prime time -- otherwise how will they aspire to a life beyond Burger King? But their parents, the restaurant staff and fellow diners should all expect proper behavior or proceed with sanctions, up to and including removal -- and the parents are the first link in the chain.

Adults may not realize that the very things they want out of a nice restaurant -- leisurely meal, low noise level, absence of stimuli -- are torment to small children.

My wife and I did take our son to a couple of very nice restaurants when he was less than one year old, but we booked 530p tables and were out of there before the main dinner rush. As my son grew older I did remove him from upscale restaurants a couple of times -- we went outside and played or went walking until our companions were done -- and, yeah, I had my fine entree out of a Styro container later on, but it was the proper course to preserve the restaurant atmosphere and the proper lesson for my kid.
