Superdawg doesn't serve Vienna hot dogs? The most famous hot dog restaurant in Chicago - the city known for Vienna dogs.?. I'm stunned. Owner said it's because they taste better, but can't help but wonder if they're less expensive.
If anything, using a custom-made, small batch (relatively speaking) hot dog would be more expensive than the much more mass-produced Vienna Beef hot dog. Whoever makes them might make hundreds or a thousand or so in a single batch compared to tens of thousands or more.
