Sienna Mercato is a restaurant in a three-story building with a different dining concept on each level. During my trip to a conference in downtown Pittsburgh, only the first level, Emporio, was completed and open for business.
Emporio's concept is gourmet meatballs and I'm usually the last person to order meatballs because they are usually lacking taste and come with the standard marinara sauce. When this place popped up on my restaurant search, I was actually excited to see something other than the standard meatball on the menu. I tried this place and liked it so much the first time that I went for a second trip. I was pleasantly surprised to see a vegetarian "meatball" on the menu as well which had a good taste and flavor. You can add a meatball to a salad or a soup or you can order one of their meatball sandwich options with your choice of sauce. If that's not enough, they also have a great variety of side dishes that you can add to your meal. The only issue was the slow service on both visits but this place made enough of an impression that I will definitely go back!
