My favorite piazza in Rome is Campo dei Fiori. It lived up to all my preconceived ideas of what a piazza should have. Open market featuring fresh and colorful produce, flowers, cafes, gelato, boutiques, outside tables, musicians, the smell of cappuccino…. a fountain… I could go on and on.
Piazza Campo de’ Fiori is where we found ourselves several times. The food just kept bringing us back. And I don’t mean the sit down at a fancy restaurant type of food either. I’m talking food you hold in your hand. No need for utensils. Food where you are delicately peeling of the wrapper its encased in… carefully balancing it between bites so as not to drop any yummy bits and pieces on the ground. Food that doesn’t cost a lot but tastes like a million bucks. And food – that you can only get in that one place and never ever get anywhere else. The thrill of the chase. The zing of the flavors.
Which brings me to the point of my story…. Aristocampo. A little sandwich shop on one of the corners in the piazza. Small. Unassuming. But a whole lot of flavor. When you enter you will see all of the best and freshest ingredients on display for you to choose from. I was a fan of their various types of mushrooms. I love fungi. Also try the porchetta, the whole roasted pig flavored with rosemary and garlic that you will see laid out on the counter. Was consistently succulent and delicious. I promise you that your eyes will roll into the back of your head when you experience the porchetta… (say it with me…porrrr-cheh-tah… I love ya).
After you make your choices – they pile it between thick slices of fresh bread and press it into the best panini you will ever have in your life. I would go to Rome again – just for these sandwiches. Yes. I truly would. 
Wish I discovered this before going to Rome!
