    Everything else was fine, got the beef and cheddar, with cheese fries- cheese fries were normal but my beef and cheddar was weird, cold, very dry and somehow the top portion of meat was actually cold while the bottom was WARM-not even hot (VERY small portion.), bun was dry and gravy and meat smells like really dirty dishwater and tastes just as bad. Thought maybe it was just me being picky but after getting the beef and cheddar 3 times I’ve learned it’s not just a one time thing. What’s making this locations meat and gravy smell and taste so weird??? Never have this problem at the one in st Charles, been eating there all my life. It’s disgusting and leaves a bad taste in my mouth.

    Their italian beef now sets the bar for the worst beef in chicago. From hot peppers that are not hot. To where's the beef? And shredded cheese thats not even melted. I dont know where to begin other than I never not finished a beef until today.. will not give this hole in the ground any more money.
