Blue Bayou, it's $$$$$ but it's good!!!! We love it there, the atmosphere and the food!!

Get a cookie boat to share, you won't regret it!
Taste Pilots Grill in DCA is a good place for CS, they have good ribs and good chicken sandwiches.
White Water Snacks in the GCH is good too, good food at good prices.
Corn Dog Castle is good, HUGE corn dogs and they are so good!! These are also available at the red fire truck on MS in DL.

We like eating at RiverBelle Terrace for breakfast, good sized portions here. We usually get 1 Mickey pancake and my 8 and 12 y.o. share it.
Cafe Orleans is good, I like the pomme frites there. Definitely get those!
We really like RainForest Cafe in DTD and the Jazz Kitchen is good too.
There is a Mimi's, a Millie's, a Joe's Crab Shack and a Bubba Gump that are close by and good too. altho the Joe's and Bubba's aren't walking distance, you would want to drive or take a cab there.
I'm sure there are others and when I remember I'll stop by and post them.
We love Aladdin, especially DBF. It's his favorite!! I really want to take him on our trip in January for his b-day, we missed it on our last trip before our AP's expired. It was the ONE thing he wanted to do so he was bummed.
