"Take the ferry from Portland to enjoy the beautiful view at this restaurant in the cove at Great Diamond Island! I definitely recommend sitting on the lawn if the weather permits. The service was excellent, and we all enjoyed our meals."

"When I visited this summer I had the greatest steak I have ever had. Our server was incredible and the view is just splendid. I cannot wait to come back once they reopen and try more of their food."

"…The views cannot be beaten: we ate on the back deck, overlooking the cove and boats moored in the marina. Great wine, great service. This is the spot where you can get authentic Maine seafood, as fresh as can be,prepared expertly and delivered with pride...”
