TheHannas, since you sound like you would like a more elegant restaurant to go, I would recommend what are known as one of the "signature" restaurants. Every park has these nicer places in the area. You can google them to see what I mean about how they are a cut above most of the theme park eateries.
When you are in Magic Kingdom, I would suggest you try one of these: the
California Grill at the Contemporary Resort,
Narcoossee's at the Grand Floridian Resort, or
Citricos at the Grand Floridian Resort. All of these are just a complimentary monorail ride away from the Magic Kingdom - just 5-10 minutes. There is even a path to walk to the Cali Grill at the Contemporary if you want to. You don't have to freshen up for these unless you really want to. However, the mild dress code just asks that guys wear a collared or polo shirt and "dress" shorts. In other words, don't wear t-shirt or graphic prints or tanks or jeans or bathing suit style shorts. And ladies, just dress nice in a semi-business casual sort of way as well.
At Epcot, there are many, many beautiful restaurants, even in the theme park area, amidst all the countries, however once again, the very finest establishments are the signatures which are just a stroll away at the Epcot Resorts. You can stroll on over when you're in the World Showcase, by the international gateway by France and walk to either the Boardwalk Resort and eat at
The Flying Fish Cafe or the Yacht Club Resort and eat at the
Yachtsman's Steakhouse.
At Hollywood Studios, you can actually eat at one of those Epcot restaurants, since they are only a quick boat ride away, or the one signature eatery they have, which is great, is
The Hollywood Brown Derby.
At Animal Kingdom, you have the option of eating at the new signature that's in the park now,
Tiffins, or head on the bus over to the Animal Kingdom Lodge - Jambo House, which is a very short ride, and eat at their signature -
Jiko - The Cooking Place.
If you're ever not sure how to get back to your resort from these resort restaurants, you have a few options - for the Magic Kingdom area resort eateries, you can either take the monorail back to the Magic Kingdom (or walk if eating at the Contemporary), for Epcot resort eateries, you can either walk back over the international gateway the same way you came if it's not too late and the buses are still running, or if they won't let you because it's too late, you can always take a bus from the resort you're at to Disney Springs and from there you can take a bus back to your resort as Disney Springs is open extremely late like till 1AM and there are always resort buses that will take you there so you can then take a bus back to your resort. At Hollywood Studios, if you eat at the Brown Derby, you won't have a problem taking it's resort bus back since they never make a theme park reservation so late that you can't use bus service back to your resort. If eating at the Animal Kingdom Lodge at Jiko, if it's too late to get back to Animal Kingdom to take a bus, you can either take a bus to a different, still open theme park, like Magic Kingdom and take a resort bus from there, or once again, take a bus over to Disney Springs to get back to your resort.
There are many fine non-signature eateries as well that you can eat it. And those don't have any dress code at all. But I wanted you to at least know about the best eateries on property since you seemed interested.
Good Luck, and do Google them all for more info!
