Bar San Calisto is located in Piazza San Calisto, 3/5 in Trastevere. This is a very traditional Roman bar that has stood the test of time and orders are still shouted to the back in a Roman dialect. Locals here favor the homemade ice cream or in winter a hot chocolate with fresh cream is enjoyed. Just a step over from Piazza di Santa Maria, Bar San Calisto is a choice favored by Romans and tourists alike.
