This dinner is located at the bottom left corner of Main Street and is reminiscent of the old-school dinners of the 1950s USA (although not being American or old enough to remember them I am basing that on the hollywood image).
In terms of decor, I actually really liked it. It is relatively simple, wooden tables and chairs indoors and similar all-weather variety outside. They may not be the most comfortable for long sitting but this is a counter service style restaurant in which you queue, order/pay, sit to eat much like a fast-food restaurant - which is essentially what Casey's is. The walls are covered in pictures of 1950s style USA sports (primarily baseball) and the restaurant is relatively bright with quite a long side of windows around one whole side of the buidling.
Apparently it can be quite busy during peak times but we tended to stagger meal times to avoid the crowds.
As for the food, it was fairly basic, hot dogs, chicken nuggets, fries, ice cream, desserts such as chocolate cake and Mickey brioche. It wasn't amazing but knowing that it was hot dogs I wasn't expecting a culinary spectacle. The hot dogs are quite a good size but the cheese was reminiscent on American cheese spray so it had very little flavour and a bright orange colour - definitely not worth the additional €0.55.
All members of my party agreed that for a snack this was a great little place to go, especially during the quieter times, and whilst not exactly cheap, it has decent food, nice decor and is easily accessible whilst heading into or out of the various lands of Disneyland Paris.
