I traveled to Cuba in 1998 and, at the tables of several families there, tasted food I still savor: pork marinated in fresh orange juice, cumin and garlic; a simple breakfast of crispy Cuban bread and newly laid eggs purloined from hens cooped outside kitchen windows. Those memories made me wonder whether Marcos Lorenzo and Fernando Martinez would succeed when they opened their Cuban restaurant, Havana Rumba, in St. Matthews in 2004.
