Those who think coffee can never be too strong should make a beeline to Kasalta, which has an amazing pitch-black brew that will knock your socks off. Make your selection from the display cases full of luscious pastries, particularly the famous quesito (cream cheese–filled puff pastry) and other tempting treats. Walk up to the counter and order a sandwich, such as the Medianoche, made famous after President Obama ordered one during his campaign on the island.
For dinner, dive into a fish dish, paella, or do like the locals and make a meal out of the savory Spanish tapas. Occasionally the quality can be uneven, and some staff members are curt with tourists.
