lunch solely because we are light eaters in the morning and like to hit the attractions early. Lunch is going to be more expensive if that is an issue. My wife and I have always had the Major Domo's Favorite Pie. Our trip in June was right before they removed it from the lunch menu. The Split Rib entree is suppoed to use the same flavor profile.
Askerhus is going to be cheaper. We always chose CRT because there is something special about it. It's not only dining in the Castle. It's being able to ride the Carousel while dressed up and having the convenience of BBB right there.
I always recommend that people base these things on their touring preferences. Some people want a big breakfast. We usually have fruit and Beignets from the resort CS. We're ready for a larger meal when lunch comes around.
