Horses for courses. Our we let our 2yo run riot at restaurants while we enjoy our food. It was an adaptation for my wife, for sure. I love it and best I can tell other patrons and staff love how comfortable our daughter is in the environment.
I suppose that would depend on the restaurant / patron.
For example, in Texas there are loads of TexMex restaurants and Hispanic cultures actually embrace children as part of the environment vs Western European cultures (which I was raised in) which don’t so much.
