A while back I had the misfortune to try the Donut Chicken Burger, which is available from Just Chicken at both Alton Towers and Chessington. Whilst it made me feel not so great for an hour or so, it made me think that the combination of fried chicken and doughnuts was possible, it was just that this wasn't it.
Here's a reminder of this questionable invention of fried chicken, bacon, lettuce and mayonnaise within a donut styled sweet bun.

Now it turns out that Disneyland have perfected the dish. In a recent video by
The Tim Tracker and a post by
WDW News Today, they feature the Fried Chicken and French Donuts at Café Orleans.
