I'd heard a lot about this spot and had high expectations. Not a Chicagoan nor do I know much about sliders or dogs so forgive me if I'm off. I'm judging on what my mouth thought.
My mouth thought the sliders lacked taste, they had zero flavor, bland, nothing, zilch. They only thing good was the bun and pickle and the garlic fries...and about those...greasy when you get to the bottom you see a huge amount of oil or butter.
Won't be back.
