congratulations-to-be!!!
I have to say the one dinner experience I didn't like at DW was California Grill. The view is beautiful at night...but the food wasn't that great. So for atmosphere I say "sure" but if you want a nice dinner..."no way".
Have you thought about LeCellier in Epcot. The food is out of this world. It's a nice restaurant and relatives that have been to France say it's just as good and some dishes are even better than the real thing. You don't have to "dress up" either.
Best Wishes!
