Cul de Sac is a popular wine bar near Piazza Navona that offers a book-length selection of wines from Italy, France, the Americas and anywhere else you could think of. The wine bottles are stacked up to the ceiling - you only need to point at what you want! The menu features a fine selection of Italian snacks, ranging from different meats and cheeses to soups, pastas, paté, dips and pretty much any taste treat that goes well with wine. The locals love this spot and it fills up very easily - so you'll probably have to share your table, but it's so worth it!
