Located near the Vatican on the famous shopping street, Via Cola di Rienzo, is a specialty coffee shop called Castroni. The coffee shop first opened in 1932 on Via Cola di Rienzo and later expanded with 6 other locations in the Vatican, Centro and other areas around Rome. While it's more of a shop rather than a cafè, there is a bar where you can order coffee and pastries. There is no actual seating area in the bar. However, the wide selection of interesting coffees, teas and other delicacies keeps your mind off the fact that you don't have a seat. BUS: 30, 280, 492. METRO: Ottaviano.
