'Get in line' on the NoWait App and make sure your reservation is for Sienna Mercato, "The Meatball Joint," and not one of the other floors of the restaurant. This is one of our favorite places for happy hour or their late night happy hour. We love the meatballs in all forms and the mac and cheese with government cheese is a guilty pleasure. We appreciate the 'birthday panini' so I suggest you sign up their mailing list ASAP. This place keeps getting better and better and I'm always dying to see their new 'Ball of the Month.' Perfect addition to the cultural district and the 'Burgh! And now the Penguins area? Dreams do come true.
