Siena is a small medieval Tuscan town, less than an hour train ride away from Florence. It is famous for their annual horse races, considered to be the most dangerous in the world for the narrow track that is established in the main square of the town. The city is divided into designated regions, signifying their allegiance to a specific horse and rider, so colors and flags are boldly (and loudly) displayed.
However, that's not why I come here. I make this a top priority day visit for one reason and one reason only - to get a few slices of my favorite pizza in the entire world. Hidden down the narrow cobblestone street of via del Porrione is San Martino Pizzaria, where you'll find locals chowing down on some of the best pies in the region. Here, you'll order from the counter and take your warm, cheap and delicious lunch to one of the few tables in this little restaurant. No frills - just perfect pizza awaiting to be devoured. Don't expect to find this in a travel guide, just ask anyone working in town and they'll point you in the right direction!
