cities across the united states have restaurants that offer themes associated with foreign countries. The U.S. embargo of Cuba keeps most Americans away from that nation, but domestic Cuban restaurants serve authentic samples of the island's food and beverages. The following ratings, based on three categorical judgments of food quality, decor and service, were collected from different restaurants in different cities. The ratings were made on the same scale from 0 to 30 (the higher, the better).
