As a kid, I loved Chef Mickeys. It was the only character dining we would do!
Last summer I tried four character dinings...
Akershus (I know I spelled that wrong, sorry!) is my new favourite, I loved the meal and the Princess interaction was great! I will definitely be doing it again.
CRT is still an amazing experience, and I think it's one that you should try at least once. Everything about it is just so magical.
1900 Park Fare and Chef Mickeys are still a lot of fun, but I find that buffet-style meals don't work as well with small groups of adults if you want to meet all the characters, so I found them quite stressful. As a kid, though, 1900 is SUCH a fun experience, so I would probably recommend that! To be honest, I don't remember the food from any of the buffet experiences, just the interaction. So it depends on which is more important for you!
