I love children and have spent almost 20 years teaching preschool. In my opinion, if by active five year olds you mean they will be loud, crawl and walk around the table, and perhaps cry or whine, I don't think it is right to take them to such a nice restuarant where people go for special dinners. However, if they can sit in the chairs and speak at normal tones, talking about kids stuff, for the 2 plus hours you will be there I say go for it. I don't mind kids in even the most fancy restuarants unless they are overly annoying. Once at Artist Point there was a family seated at 8:30 with two young children (under 6) and they squeeled at the top of their lungs for the next 30 mins until we left. The parents just ignored them. I don't think that is fair to the other diners.
