Hi
Our recent experience at California Grill maybe relevant here, it was the second time we had visited. My (young) daughters have always wanted to look nice and wear a dress for such occasions, this is possibly down to me telling them it's a special restaurant, with excellent food, service and at a price that reflects this (my 13 year old's $49 pasta and steak bears this out.) My wife and I dress accordingly with pants and a collared shirt for me for example.
However the party of 10 arriving direct from the park at 8.00 pm, six adults and four children, did not have the same view as us. Now I totally agree that this should not spoil what is a great meal in a great restaurant. Personally dressed the way they were, in clothes that had been worn all day and looked it, would have made me feel 'out of place'. My problem wasn't even the fact they needed to charge their phones, so plugged these in behind our table while we where eating. It was down to one lady who every time she got up, had to adjust her skin-tight shorts in the crotch area and adjust her sweaty tee shirt in order to retrieve her phone to photograph the food she was receiving before I assume posting on Facebook. She got up often!
So while there is a published dress code I think you would have to turn up in swim wear before being turned away.
I doubt if Disney would miss our custom so I don't expect anything from them to make this a signature dining experience with an enforced dress code that complements the experience.
We'll be back at Disney next year, wouldn't miss it for the world, however I think we will give that experience a miss this time.
Regards
Paul
