The fair I had gone to in the spring had those glazed doughnut burgers, too. The most disturbing part of this experience was being told that they hadn't tasted half bad.
So.. half bad, as in half of the burger is pretty tasty and the other half tastes bad? No- no, apparently it's not nearly as tasty as a traditional burger but, for what it is~ This was followed by a smile and noncommittal shrug, which tells me that this insanity might even continue.
But it's.. eww. On what planet does a doughnut burger taste good?
