Was looking forward to a trip to Mezzo as Sienna on the Square is one of my fav Italian restaurants in Pittsburgh and this is essentially a sister. The service started out poor and continued throughout. Based on my observation it appeared they were understaffed for the crowd as our waiter had numerous tables. We were going in advance of a show and after we waited 22 minutes to get our waiter's attention after our reservation/seating time, we were finally able to order drinks for the table, along with food. My husband and I arrived earlier than the other couple and he ordered a drink which took nearly 15 minutes. We made it clear to our waiter that we were going to an 8pm show so after waiting 22 minutes for any attention, we'd need to be accommodated. We were quickly told too bad and that everyone in the restaurant was going to the show. We finally received our entrees at 7:46pm (or reservation was at 6:30) which meant we were forced to shovel the food into our mouths. It was a damn shame because we all agreed our dishes were outstanding. This is the only reason they received any stars. Kuddos to the kitchen. Front of house needs to get their act together. I don't think this was the fault of our waiter but poor management of the wait staff. The wait staff were working their tails off for basically a bunch of unhappy people.
