They say that Costa Rica is the Switzerland of Central America. Then Nicaragua must be the Argentina of that historically embattled isthmus. Why? Churrasco. You know, charbroiled beef. The Nicaraguans are as crazy for it as their Southern Cone cousins. But whereas the Argentines often credit Italy for some of their culinary inspirations, the Nicaraguans tend to look north. Hence dishes such as tenderloin tips a la jalape?a (i.e., with a creamy jalape?o and onion sauce). You, however, need only travel west a few miles to this modest yet elegant establishment on West Flagler and SW 107th Avenue. The menu also offers a wide variety of appetizers and chicken, pork, and seafood entrées. And ask your very cordial waiter for that spirit enhancer that crosses all north-south divides: a carafe of sangría.
