I have dined in CK many times. Overall I have found Luminae to be of better quality...actually I always find Celebrity food to be of better quality overall. Celebrity has more $ to spend on dining compared to Royal so really not that surprising. Royal has to spread out their $ to more areas to pay for all the bells and whistles. Actually my favorite is Blu...even over Luminae. But yes....food is all subjective and can vary greatly from sailing to sailing...ship to ship.
