With an 8 yo, if she doesnt mind some funky food or vegetables, Teppan Edo is definitely the place. The chef's are good (when it comes to hibachi grills) and they'll keep the kids entertained. I know my little brother at 8 wouldnt have minded Teppan Edo, but I was one of those chicken fingers and pizza kids. Either way, the food is excellent and the preparation is awesome.
My personal favorite is the Rose & Crown with a 7:30PM or later dining reservation. When you see the hostess, ask for an outside table. That way you can eat, then enjoy dessert while watching Illuminations. Le Cellier is a no brainer as well, always GREAT food there.
