We just sailed on Voyager and ate MDR 4 out of the 5 nights. I never had a bad meal. I actually enjoyed the MDR more than our chops dinner on night 4. Our waiters Nandy and Melvin were absolute rock stars and really made the experience. We never waited on drinks and always left stuffed. I ordered the Filet I believe on night 2 and when Nandy came over he said "Looks like you enjoyed your steak, would you like another one?" Hands down best MDR experience we have had.
As much as I didn't think I would like the themed menus I have to admit it's not that bad. I miss the desert options the most but it made me try some new things.
