...I agree with the notion that if you have one anywhere near where you live, go at home and skip it at Disney. We will probably do RFC because of the atmosphere but in all honesty, the food isnt really that great, its overpriced, super crowded & seating is usually really close together, and we haven't really gotten great service ever. The closest to really good service was for breakfast at Animal Kingdom so you might want to opt for that - the food was better then too.
Hate to be a downer, but wanted to give my POV too. Like I said, if you go for the atmosphere only and to see the kids get excited you will probably enjoy it - just dont expect too much in the quality or service dept.
