Just incase when you are there you decide to try either 50's or Sci-Fi.
My son is quite shy and I was a little worried about 50's as I have been there before without children so I knew what they are like but I was very impressed both times we went. Both servers picked up what he was like and really were not over the top with our table, they were over the top with most of the tables around and my son had great amusement watching, but I was really impressed at the way that they just picked up that he wasn't into the OTT thing and just played it down. Plonked down the cutlery etc and asked us to set the table before dinner (but wasn't loud like with the other tables). Neither times did they try to feed my DS, but he cracked up at watching the tables beside being fed. I think they are trained to pick up if people are not that into it. I love it there, the Chicken pot pie is so delicious.
Sci-Fi is also great. Sitting in the cars is so much fun, being seated by somebody wearing rollerskates was fun and the movies are ok for kids to watch, it is disney so there is always something for the children, it isn't horror movies or anything, some of the movies were quite cool and they have yummy milkshakes
I'm not saying they are must do's (they are for us, but that's personal preference), just wanted to let you know for when you are there, and at the time you were tossing up about going, if you wander past and are able to get a table, just thought I would let you know that they are both ok (food is hardly gourmet, but it's ok, its the atmosphere at both places that takes us back)
