Do you want to be in Epcot?
If so Garden Grill will be the closest to a traditional Easter dinner. For every person that dislikes any restaurant in WDW there is someone else who loves it. It's so hard to take advice on food from people that you really don't know anything about. We all have such different tastes.
I almost didn't book Ohana the 1st time b/c the of a really bad review from this site (not posters, but the review on wwwinfo.com). I gave it a try and it's one of my family's favorites.
My new theory, is if you like the menu, then go for it. If you don't like the menu, you still may like it (for us we love Akershsus). I picked it for the princesses, not for the food, but ended up liking the food.
Have a great trip.
