Shackmeister Dog at Shake Shack
We thought this special Shack dog was a new addition to the menu but it now seems like a limited time item as we can't find it anywhere. But maybe it'll come back sometime. If so, consider eating it: A Vienna beef dog split and grilled on the flat-top in a potato bun with fried onions and lots of that cheese sauce that makes Shake's Shack otherwise pedestrian crinkle fries taste so good. It's a messy treat.
