Shutters? At Vero Beach?
Its really the only restaurant at the resort besides the Pool Grill. We ate there a lot during our stay. Breakfast/Dinner. I thought it was nice. The menu wasn't expansive but what they had was very good. We had a stone crab special, and the iceburg wedge was good.
I don't remember the sandcastle icecream. They had a make your own sundae with the different cups for toppings. DD Loved that.
Hope that helps.
Editing to add, there is a vero beach adoration thread on the DVC Mousecellanous board. There's a lot of info about Vero and surrounding restaurants. (Not that Shutters was bad, but if you are there for a while..you might want to venture out.
