Little Havana is changing. It used to be difficult to take the red peppers and mix them with the green, blend the onions with the grilled chickens and luscious strips of beef. But no longer. In a post-Elian world, you can bring it all together under the cover of a warm corn tortilla. Remember, fajita comes from the Latin word fascia, which means band, as in band together. So if you're going out for a little dialogue with your friends, why not stop at this Mexican restaurant, see the new Little Havana, and put all the ingredients together at last.
