I just called my nephew (who was 10 when we went in April) and he said that his favorite meal from the trip was the Hoop-dee-doo revue. It's a lot of fun and we thought that the food was very good. They performers roam around the audience and ask if there are people celebrating so they can sing to them all, etc. It was really enjoyable for the whole family.
On the same trip we celebrated my 5 year old twins birthday at Chef Mickey's and that was also very fun - the whole family enjoyed that too. The character interaction there was great, the kids got a special birthday placemat, and at one point Pluto was at the table with them while they were singing the birthday song.
