I think it kind of ruins it for the people who really do have well behaved kids, especially if they don't have ayone to babysit. I am one of those people, and I'm still upset that I can't go to restauraunts that have a bar because it's illegal here for anyone under 19 to enter, so I can't go unless I go by myself because my hubsand would have to stay home and watch Tyler and I don't have anyone to go with. With the few restaurants in our town that don't have bars, it really limits our choices and we usually have to end up driving to one of the other cities around us, and that gets expensive and inconvenient. I can't imagine if the other restaurants here banned kids too.
But, that's me.. I have a really well behaved girl who has eaten out with us once or twice a week since she was born, and only one time has she ever started crying in the restaurant because she was 3 months old and tired; I simply took her outside, nursed her until she fell asleep, and brought her back in and she slept on my lap while we ate.
I have a friend whose child is absolutely crazy and so she doesn't take him out to restaurants. I think that's responsible.
I would rather see the restaurant manager tell people that they've had complaints and must pack up their food and leave, as opposed to banning every child from the restaurant, because it's really not fair to those who really do have good kids.

While it's ok to think it's only ONE restaurant, and that's not too bad because there are a million other restaurants to eat at, it's like saying that it's only ONE city banning pit bulls -- that's ok, there are a million other cities to live in, right?... Responsible parenting is the same as responsible dog ownership. If your kid is bad in a restaurant, don't take it there. If your dog is aggressive, don't let it run loose. Don't punish an entire breed for the few bad apples and don't punish every family either.
It doesn't just stay with ONE, people follow.. The more rules that are enforced, the more people will follow, the less options we have. I don't want fast-food restaurants to be the only place I can take my kids. It's not healthy and doesn't cater to my or my daughters' food allergies.
However it other restaurants were to have a Playplace LIKE Mcdonald's... That would be great lol..
