Hi there Kathy,
In general, the dining experiences that are located
inside the parks will not require a "special" dress code. Disney has kept in mind that when guests are inside the parks, they usually enjoy the park either before or after dining in one of their restaurants and will normally not wear or bring "dressy" clothes while there. Park attire is what would be required here, but I always like to be, what I call, "formal casual" when I know I will be dining out anywhere, but that is just me and what I like to do, (my personal preference). As far as Chef Mickey's, I have eaten here many times and "park attire" is just fine for this one as well...so you are good-to-go!!!!!
In case you are wondering which restaurants have a dress code, please visit this
link for some of them ,(I know that
"Victoria & Albert's" is not listed here and
is included in the "dress code" list), as well as what they "mean" by dress code by clicking on the restaurant and scrolling to the bottom of the page where you will find this information. I hope you have some wonderful dining experiences and a magical stay!
Best wishes,
Brigitta
