As others have said, there are a lot of places at Downtown Disney in Anaheim to eat. If you're more on a budget you can try the take outs for Tortilla Joes and Napolini. Disneyland Hotel has Tangaroa Terrace and Trader Sams that you might want to try, and there is Whitewater Snacks at the Grand Californian that is pretty reasonable. I stayed at the Clarion Hotel during D23 Expo, and we walked down to a bar & grill called Clancy's Clubhouse - American fare. It was pretty good, and I'd go again. There is also a Gardenwalk with different places to eat like California Pizza Kitchen, Bubba Gump, etc., and going down Harbor near the Tropicana is Pizza Press that gets a lot of good reviews. Of course, there is Mimis, and Panera is opening soon (not sure when you're going to be there.)
