"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."
