I've taken my children to most of the nicer WDW restaurants, California Grill not being one though. What I usually do is make the first ps available, and then we go in. My kids are used to eating out (we go out usually 1-2 times per week) and know how to behave in a restaurant. I do the earlier time so they aren't tired and cranky by meal end. I NEVER would consider going to California Grill around a late fireworks time with my kids, they NEVER would make it. If you don't mind eating around 6:00, I don't think it would be a problem, anything much later probably would, unless your child is a nightowl. I started taking my kids to the nicer restaurants at age 8 months, and they are now 2 and 5 and LOVE THEM. DD looks forward to the white chocolate Mickey puzzle at Artist Point now, and the multi-colored bread at Jiko.
