The new menu item is already extremely popularMost Walt Disney World restaurants easily accommodate vegetarian and vegan diets. Casey’s Corner has always been an exception; until a few months ago. Now a Plant-based Dog is on the menu, and it’s a hit! (That’s a baseball pun, by the way.) You can get it loaded with slaw and more if you’d like. It’s vegan as is, and comes with fries (that are cooked in a shared fryer) or apple slices.
