I don't know of any specifically, but I did eat once in a terrific little Dominican restaurant in Chicago, and talked to the owner, who seemed very keyed in on all things Dominican going on in Chicago. I would suggest going in there for dinner and asking for more info once you're there. The restaurant is called Punta Cana, and is located at 1024 N. Ashland, and the website is www.puntacanarestaurant.net, or do a google search.
