I have sailed on Galaxy, Mercury and Millennium and the food was great on all three. I think (hope) you just hit a bad week. I would highly recommend the "specialty restaurant" on Summit. The Olympic on Milli was outstanding...well worth the charge.

The food on my recent Infinity cruise was not up to par, and we are sailing on a different cruise line next year. (we had just completed our 7th consecutive Celebrity cruise), but the quality(i blame it on RCI) and selection along with presentation of food was "average" at best.
I also perfer the size of mercuy and felt the infinity had "no warmth" or personality.
This observation was also made by some of the crew and passengers that were veteran celebrity passengers while sailing on the infinity.
