Even in NY there is a Dominican food place on the corner of Park Place and Nostrand Ave and a Jamaican place across the street on Nostrand Ave. No comparison. The Jamaican beef stew is a huge mountain of meat and sauce on 3 types of rice available. The Dominican beef stew is a huge mount of rice, 2 available, with a smattering of beans and a couple of chunks of meat. If you are paying $6 for a small plate the Jamaican place is where you would go to get full. The Dominican place is just for nostalgia.
Well, that Dominican spot in BK is definitely an outlier, certainly not the case with most Dominican establishments, which are usually very generous with their portions, not just with rice and beans but also the main dish or protein. Stewed meat is one of our main specialties so to hear a place only gives a few chunks of meat is unusual.
