So what is your absolute favorite single food item at Disneyland? I think we'll limit it to just Disney properties, so that would be both parks and the three hotels. I think my favorite would have to be Corn Chowder in a bread boulle at the French Market. On the rare day where the park is open late and the restaurant is not horribly busy, it's fun to get that and watch Fantasmic (or what parts of if you can see) from the dining area. Before the remolded the Cafe Orleans I would have said the mufaletta, but unfortunately I believe it's been gone for several years now.
Also, I haven't tried the carne asada burger at Grand Californian yet but that's #1 on my list next time I go.
