Don't know how this got to be a 'pro' and 'anti' kid thing, but for what it's worth, when I take my grandkids out for a meal, we go to places that cater for kids. When I go out for a meal just me and hubby, I prefer to be in grown up company. My choice and my preference. I enjoy both experiences.
My grandkids would hate to go for a 'formal' meal (they are 2, 4, and 8), just as my hubby isn't too impressed by the informal and generally noisy meals when we take the youngsters out.
Just as I wouldn't take children into the workplace and expect them not to cause some disruption (no matter how small), I wouldn't take children into a formal, 'grown up' restaurant.
When my own kids were little, I used to like to go out to 'de-stress'. Child-free zones so that I could re-charge my batteries. I also used to like to take them places with me where both they and I could enjoy.
Can't see anything wrong with that??
