Just at
Disneyland (not including DTD, CA, or any of the hotels...which leaves a few favorites out):
Gumbo, pommes frites, and Mickey beignets at Cafe' Orleans.
Chicken or turkey pot pie and loaded baked potato soup at Carnation Cafe'.
Mint julep from any of the places that sell it in New Orleans Square.
Gumbo and scalloped potatoes at Blue Bayou. (Unfortunately, they got rid of the cookie boat dessert

)
Mickey pancake from Riverbelle Terrace.
Chicken fusilli with parmesan cream sauce, minus the chicken (not a vegetarian but chicken + cream sauce...one or the other is ok, but not together

) from Pizza Port.
Various candies from Candy Palace and Pooh Corner. Especially the dark chocolate mint patty!
And a new favorite, as of last trip: the teriyaki chicken skewer from Bengal BBQ.
