Coffee is a high art form as they come in Puerto Rico, and Cuatro Sombras in the southern part of Old San Juan brews a particularly fine cuppa. Start your morning adventure in the colonial town with a hipster-friendly latte and toast slathered in sweet guava butter. On your way out, purchase a bag of Yauco-grown beans to keep yourself caffeinated back home. #coffee #sanjuan #puertorico
