Downtown Disney is a dining, shoping and entertainment district that spans from the theme parks to the Disneyland Hotel. There are a number of carts, quick service, and table service dining options.
The Geek's Suggestions
If you are looking for something different than the parks but still within a short walk give Downtown Disney a try. Prices vary with some kiosks/take out slighlty less than in the parks, table service is on par with the hotels and parks.
