TS is either The Plaza or LTT since they are both pretty good and neither has disappointed us before (Tony's and CP were just awful in every aspect of the meals and we were not crazy about the food at CRT but that was before they altered around the menus a bit and the overall experience is pretty awesome). As far as CS, our favorite place is upstairs at CHH. The food is pretty good and it tends to be real quiet upstairs which gives you a great chance to relax and regroup.
I don't like the TS restaurants at MK (I don't do character meals and two of the five are character meals), with the single exception of Liberty Tree lunch and I haven't been to that for awhile.
