We just got back from our trip, and we were staying at CBR. We had not planned on eating at Shutters as we were not on a meal plan, but one night Dh decided he wanted to try it. And it was fantastic! I'd definitely go back. Dh and I both split a Ceasar Salad, Shrimp Fritters (yummy!) and the Caribbean Pasta... all were very tasty. Our dd had the kids cheeseburger and it came with a very fun make your own sundae. She loved it. My absolute favorite item though, was a smoothie, which I believe was called Raspberry Lava or something like that. OMG! So good!
Before planning our trip I too had read mediocre reviews on Shutters, so it was not a must do. But I don't know, we love it! And the service was the absolute best we had all trip. Our server was the most upbeat and friendly woman at Disney! lol...
