San Telmo has what feels like dozens of bars on every corner, but Nilson is one of our newest favorites. It’s not a big place, but that’s fine since the best seats are outside on the cobblestone street with a great view of the San Telmo Market. It’s the ideal place to stop and check your step count after walking around the famous Mafalda statue, sip an excellent pinot noir, and snack on some cheeses. They serve wines from nearly every wine-producing province in Argentina—Mendoza, Salta, Cordoba, Río Negro, Neuquén, Chubut, and beyond—and have a by-the-glass menu that changes weekly.
