I'm not discounting anyone else's experiences or opinions, however, I seemed to have a very different experience than many others. We've been on Symphony and Oasis this year, both with the new menus, and both times we enjoyed the MDR. I'm not going to say it was gourmet quality food and I will agree that the shoe-sole-sized "McRib" steak was not great. However, we enjoyed at least one entree each night, often enjoying several between the two of us. We also found the service to be terrific. All in all, the MDR is part of our cruise experience that we enjoy.
In reference to the cold food for MTD cruisers. Someone much wiser than me pointed out that it seems the kitchen caters to the two main seatings. The further off your MTD time is from these times the less consistent the food quality and temperature. That's not an excuse, if RCL is going to offer off-time MTD then they need to up their game in executing it.
