For us the food is quite similar even though CRT has that stuffed french toast thing, IMHO, both places were a bit greasy of a meal.
The atmosphere and location of CRT can't be beat BUT we enjoyed both places and actually had more Princesses at Storybook.
I'm going to book Storybook and also try to get CRT, and if I get CRT, I'll probaby keep it, BUT I'm not going to stress about it or go crazy trying all day long everyday to get it because Storybook is VERY nice too.
I hope I helped you a little bit!
