Dining Outside the Home: Old Town Mexican Café in Key West, Florida! When a restaurant boasts of an abundance of hatch chiles and fresh, local ingredients, you begin to wonder if Santa Fe style Tex-Mex might be a good choice for dinner. Anytime the weather is hot, and the drinks are cold, it draws a crowd on Duval Street for seafood favorites, like skewered shrimp marinated in lime juice and ginger. Take a swig of on-the-rocks margarita. The salted rim offsets the spicy salsa you can’t resist tasting now and then. If you’re in the neighborhood, take advantage of Happy Hour specials. There’s no rush here.
