Fodor's Expert Review Castroni
Opening its flagship shop near the Vatican in 1932, this gastronomic paradise has long been Rome's port of call for decadent delicacies from around the globe; there are now 13 locations throughout the city. Jonesing expats and study-abroad students pop in for local sweets, 300 types of tea, and even some good old-fashioned Kraft Macaroni & Cheese. If you're just doing a little window-shopping, be sure to try their in-house roasted espresso, some of the best coffee in Rome.
