Since this thread is what "Disney" is famous for and not Disney World, I am going to have to say Churros. While I hardly saw any for sale when I was at WDW, they are EVERYWHERE at DL!! And the lines are usually very long. And they are usually VERY tasty- I bought one at DtD in early March and it was a disappointment- it was hard and stale. However, when I have bought them at DL, they are crispy on the outside and soft and chewy on the inside- bliss!
