After my experience with the Iowa Machine Shed in Davenport (first one in the linked site) I give the Stalking the Wild Tenderloin site little credence. From
my post on a trip in 2004:
The final meal on the trip was lunch at the Iowa Machine Shed in Davenport IA. We planned to stop somewhere in the Quad Cities. It was time for lunch, and this restaurant was very close to the gas station where we filled up. It is as kitschy as Cracker Barrel but uses mostly farm equipment. Water and iced tea are served in canning jars. Light level at lunch was much higher than Cracker Barrel. My wife had a good fried catfish sandwich plus thick beef-vegetable soup. Still with wishful thinking, I tried their version of pork tenderloin sandwich, which the menu says is their best seller. The batter coating that worked so well on the catfish was all wrong on the pork, which was the flaked and formed stuff to boot.
Cathy2's assesment was dead on.
