I have to concur with your opinion after my last cruise on Spectrum in March. I had an absolutely awful starter at chops grille and left most of it on my plate. When the waiter came and cleared it up, I mentioned to him that the starter was awful and he simply cleared it without even offering to replace it. Worse off, we were limited to one starter per person despite having multiple during previous cruises. I'm not sure if this is the norm moving forward.
To concur with your statement, my experience too with the steaks in the MDR were of such low grade beef that I couldn't even bring myself to finish it.
In both specialty dining and the MDR, waitstaff kept stressing about the end of cruise review and giving high scores that it left a bad taste on my mouth. The interactions with staff felt extremely forced and a little unnatural. This is in stark contrast with our cruises on Royal in the past where staff felt genuinely friendly and happy. Crossing my fingers that I will not regret going forward with the 12n on Anthem next year.
