I didn't understand what "Chicago" style tacos meant. I'm from LA so I guess I assumed people in Chicago don't eat tacos! J/k.
I didn't eat much, so I can't comment on the beans and rice. I had a Carne Asada taco. The tortillas were very soft, the meat was well seasoned,and the salsa was the best! Too bad no chips to dip....but it is a small taco shop. I will have to go back to try the breakfast burrito.
