Hi there, Chicago Hounds!
I was born in Chicago and moved to LA years ago as a kid. One of my favorite Chicago foods is an Italian beef sandwich. My dad would bring them home after work and they came from little mom & pop places on the West side. I have no idea the name of the place. I know Portillo's wasn't in the beef sandwich business at the time.
We, Chicago ex-pats on the LA board, would be interested in your thoughts on the best Italian beef sandwich in Chicago.
