One of the most popular coffee houses in Old San Juan is Cuatro Sombras, a place that prides itself on its farm-to-cup operation and the high quality of its single-origin 100% Arabica coffee beans from Yauco. Their medium-bodied brew has hints of semi-sweet chocolate, spices, and caramel flavors. The trendy shop also serves sandwiches, paninis, salads, and pastries.
