Admittedly I would not know the difference between Maritime or Caribbean lobster, nor would I know the difference between prime & choice beef. What I do know is that I have ordered the included steak from MDR that was better than what I got from Pinnacle. I don't eat seafood- so chicken, pork or beef are always my choice. I have ordered many a steak in MDR, sometimes it is tender & good, other times not so tender. Just luck of the draw I guess. They had steak on lido a few times on our recent 10 day cruise- usually pretty good.
