Having just come back from Chicago, I wanted a Chicago Hot Dog and there's a place right downstairs from where my Dad lives. I took my kids there and it was closed. ...much disappointment.
There is a place in Fort Lauderdale on Sunrise that I used to go to like once every two weeks when I lived there and whenever I visit back in South Florida, I still try to get there. They do really good Chicago dogs. It is called Hot Dog Heaven. Just a tiny little place, but it has always been my go-to hot dog spot. Here in Dallas, I am completely unable to find a decent hot dog or pizza. Thankfully, I don't eat that stuff much anyways, but for a workout cheat day, it would be nice if I had a decent hot dog or pizza option.
