We had dinner at all 3 of these character meals on our January trip. We loved each and every one

.
Crystal Palace was our favourite of the 3. Best food, nicest atmosphere, excellent service, and soooo convenient to eat right at MK.
Though many other posts complain about the quality of the buffet offerings, we also enjoyed 1900 PF and CM's. Both had lots of choices for everyone (young and old) that were hot, fresh and plentiful.
1900 PF was definitely the LOUDEST of the 3 meals. With all the antics between the stepsisters, this is not a good choice for those looking for a peaceful dinner. But it was fun and entertaining! And we all found lots and lots to eat here....despite the fact that two in our party are very, very finicky. Was it gourmet? Nope. But it was a satisfying meal with something for every taste.
CM's is great because you get the Fab 5 all in one place....fantastic for autographs and pictures without standing in line at the parks. And their dessert buffet was superior, in our opinion, to that of 1900 PF (DS loved the make-your-own sundae bar).
Still, though, CP took top honours in our opinion. Everything about that meal was awesome!
