The only time I ever saw a child at an evening dining/wine event, it was at an Exquisite Evening at Epcot (these events were wonderful, but are no longer held). A couple brought their baby in a buggy. They were up and down throughout the entire evening keeping the baby quiet. To their credit, the baby never disturbed the dinner, but I think the couple ended up having a stressful evening and actually could not have enjoyed the food and wine much at all. Since the evening was about $185 a person, it seemed like a waste.
Upshot -- the signature dinners, the French regional lunches, the wine schools, etc. are really only for adults.
