I am originally from Chicago, and I have discovered that a good Italian Beef sandwich is very hard to come by outside of the Chicago area. Enter Portillo's a Chicago-based restaurant. I love the Beef and Cheddar Croissant. It is what I order from Portillo's almost every time I am in one of their restaurants when I am back home, and it wAs a very pleasant surprise to find a Portillo's in the desert!
The food is great and the service is pretty good. I was thrown off a tad when i ordered my sandwich sweet and wet, a term that most Chicagoans would easily understand, and the young lady behind the cash register looked at me like I was crazy. Fortunately, I was able to translate the lingo into layman's terms pretty easily, and it got me one of the best Beef and Cheddar Croissants that I have had.
