Following up my original post with some pictures as I returned today for lunch.
I have verified that they are one and the same as the location on Devon. They are closed on Tuesdays for food prep, and they do catering.
Today my co-worker and I stopped in and together we ordered a cuban empanada, cuban sandwich, a side of fries, a side of rice, and the ropa vieja special with black beans on the side.
(Apologies in advance for the bad camera phone pics)

Cuban Sandwich
The Cuban sandwich today was cooked a better than last week, as you can see the darker browning on the bread. The bread was dry and crispy, the cheese melted, and the meats blended together for a delicious Cuban.

Cuban Empanada
The empanada was fresh and hot, the pastry was light, flaky, and crispy, and it had a wonderful flavor. The green hot sauce was a good complement to it.

The Ropa Vieja
This was very delicious, the meat was tender, not dry. The sauce was great and the portion was huge. I couldn't finish it. The side of black beans was good as well, had good flavor and not bland.

Side of rice
Really good rice. My friend had it along with his Cuban (which I got to sample) the portion was large, and he had to take half of this home.

Fries
Good fries for what they are. Thick and well cooked, but I enjoyed the other stuff better than the fries.
Overall, glad to have this option in Schaumburg now.
