"Set in a 19th-century building in the former Spanish military barracks, Café Don Ruiz, which abuts a plaza, is a great place to begin a day filled with history and culture; after all, even the drink will come from a fourth-generation coffee grower. Browse the collection of antique coffee-making tools and roasting equipment in the café, then perhaps visit the Museum of the Americas, which chronicles the history of the American continents and the Caribbean, just upstairs. The iconic El Morro fort is right across the street." - Kathleen Squires
