For the most part, Disney food is "serviceable" to "good". Service likewise.
I can't recall a truly bad meal, or bad service experience. Some have been better than others. But, nothing has been amazing, or worth a detour. Fine places to eat at if you are in the area.
To be fair, we haven't yet tried some of the nicer resort restaurants, the Jikos and Artist Points of the World, but perhaps someday. But, so far, the meals and service haven't been markedly better than I can get here in my modest little college town.
On the other hand, the "experience" meals (character meals, Sci Fi, Coral Reef, etc.) have all been really unique, and fun experiences. And, so, we find that we book one or two such meals every three days or so.
We tend not to do much other Disney TS dining. So, even though everyone raves about places like Le Cellier, we don't bother, because we've got a couple of great steakhouses here. Same with, say, Tony's. I can get mediocre Italian food for much less at home; why should I pay top dollar and kill 90 minutes in the Magic Kingdom for the same thing?
