We stopped in on a recent visit to Pittsburgh. First, the doors were wide open and it was at least 80 degrees and very humid in the restaurant (90 degree day in August) but it was just about the only place open for dinner late at night. We asked the waiter for a table in a "cool" (meaning, with some AC) spot in the restaurant - i would hate to see what the other options were. We ordered a variety of starters to try - the cheesy bread, pickle chips and Caesar salad. the cheesy bread was ok, literally just crusty bread with some cheese and marinara for dipping, i wouldn't order it again. the pickle chips had no taste except that of salt. we probably each had one bite and then pushed it to the side of the table to forget about. the Caesar salad was actually really good, yet simple. the dressing tasted slightly lemony and i really enjoyed it. i then tried a single turkey meatball slider which was, again, just ok. the meatball itself had no flavor, but the marinara packs a punch. we had a lot of leftover food but the waiter never inquired about whether anything was ok or asked how the food was. the only thing that i would order again was the salad, which means I probably won't be returning to Sienna Mercato.
