is the food complimentary or is there a charge?
Please, lets not go that far
You can easily get in and out of the CCR to the T5 shops.
The dining room is as formal as it gets, and that's hardly what I would call 'formal', but if you want to lounge on a sofa inside or on the terrace, or in a Cabana, you can choose to have things from the menu brought to you there.
Enjoy ^
