You’ll find plenty to love at Sienna Mercato, a three-level Italian restaurant that boasts a different concept on every floor. Wood-fired pizza and a rooftop bar are available upstairs, but the ground floor devoted to meatballs is where you'll want to spend most of your time. The menu features four classic balls (beef, spicy pork, chicken, and vegetarian) and about a dozen sauces to pair with them, like creamy Parmesan, arrabbiata, and mushroom gravy. If solo meatballs aren’t your thing, have no fear: you can get them piled on top of mac & cheese, mashed potatoes, spaghetti, and more.
