No trolling, please.
No one bakes Cuban bread anymore in Chicago, and even Marianao uses a product from Gonella (might be made to M's specs, but it is not quite right). Las Villas, the bakery, used to be Cuban and had ok Cuban bread. It is no longer Cuban, but might still make it. It has been a long while since I set foot in Las Villas, however.
Bread requires people to buy it, and for whatever reason, no one demands real Cuban bread here (or anywhere outside of Florida for that matter, and by this I include NY, NJ, and CA).
Some of the lighter-crusted Italians make good substitutes. Somewhat ironically, Il Liborio (Italian name with big Cuban implications) in particular.
