One of the blog entries over the summer was a review of Shutters, and the review suggested it was an abysmal dining experience. We stayed there last year with my mom, and she's spicy-food-phobic, sonar didn't try it. It didn't ever have many people in it, though it was October.
The CS places seemed average. I had a western omlette one morning, and it was decent. I don't intend to eat there again this year, though - there are better CS throughout he resort.
What we ended up doing is using our snack credits (regular dining plan) for a bagel or other breakfast item, and then the rest of our meals were in the parks.
The rest of the CBR experience was AMAZING, though - definitely the best hotel/resort I've ever been to! Have an awesome trip!
