At first glance the gustatory enticements on this stretch of Biscayne Boulevard seem flatter than the landscape. The eye gets caught on the bright ubiquitous colors and familiar logos of McDonald's, KFC, Subway, and Taco Bell and sees little else. But the neighborhood also boasts eateries that speak not to the comfort of national fast-food dining but to the richness that waves of immigrants have brought to Miami's cuisine. Within a few blocks there is Honduran, Nicaraguan, Peruvian, and Haitian cuisine served at the kind of down-at-the-heels-looking joints that you pray have great food. Housed in a building with a lime-green shingled awning on the corner of 30th Street and Biscayne Boulevard, Delicias del Mar Peruano offers fresh seafood seasoned with lime, basil, mint, garlic and other pungent flavorings. Portions are large enough for two. The fiery jalapeño salsa with sliced baguettelike bread is worth a visit alone. The restaurant prepares six kinds of ceviche, heat adjusted to order; seafood soup (with octupi, large shrimp, and mussels in a clear broth); and perfect arroz con mariscos (shrimp with yellow rice) with flaky rice and just-cooked shrimp. Open for breakfast, lunch, and dinner, just like a neighborhood restaurant should be.
