The city offers a mix of contemporary restaurants and spots where you can savor authentic island flavors.
Mofongo
Mofongo is arguably the most famous Puerto Rican dish and a staple you'll find throughout Guaynabo . It consists of fried green plantains that are mashed together with garlic, olive oil, and pork cracklings (chicharrón) in a wooden pilón (mortar). The result is a flavorful, starchy mound often served with a meat or seafood broth on the side, or stuffed with fillings like shrimp, chicken, or beef. This dish is a delicious representation of the island's culinary history, with roots in African fufu and Spanish influences . It's a must-try, found in many local "criollo" restaurants as a hearty and satisfying main course.
Alcapurrias and Bacalaítos
For a taste of local street food and beachside tradition, you can't miss alcapurrias and bacalaítos. These fritters are the stars of the chinchorreo experience—the local tradition of hopping from one food kiosk to another . An alcapurria is a torpedo-shaped fritter made from a dough of grated green banana and yautía (a root vegetable), which is then stuffed with seasoned ground beef or crab and deep-fried until crispy. A bacalaítos is a large, crispy fritter made from a simple batter of flour, water, and parsley, studded with chunks of salted codfish. While famously associated with the kiosks in Piñones (near Carolina and Loíza), these treats are widely available and represent the quintessential savory snack of the island .
Piña Colada
No visit to Puerto Rico is complete without enjoying its national drink, the Piña Colada . This iconic cocktail, a creamy blend of rum, coconut cream, and pineapple juice, was born right on the island. While its exact origin is debated between bars in Old San Juan, its status as a symbol of Puerto Rican refreshment is undisputed. You can enjoy a perfectly crafted Piña Colada at many of Guaynabo's hotels and restaurants, offering a taste of the tropics in a glass.
Pernil and Arroz con Gandules
Pernil (slow-roasted pork shoulder) and arroz con gandules (rice with pigeon peas) together form the cornerstone of any Puerto Rican celebration, from Christmas to birthdays. Pernil is a labor of love: a pork shoulder marinated for hours or overnight in a garlicky, herbaceous paste called adobo mojado, then roasted low and slow until the meat is impossibly tender and the skin is crackling-crisp. It is traditionally served alongside arroz con gandules, which is rice cooked with pigeon peas, sofrito (a fragrant blend of culantro, ajíes dulces, onions, and garlic), and sazón for its signature golden color . This combination is the ultimate expression of Puerto Rican comfort food and a must-try for anyone wanting to experience the island's soulful cuisine.
