This is a very good ballpark to watch a game at. I was in the nosebleeds on a free shirt Friday and it was a great time. It's hard to beat the atmosphere with the skyline of the city off in right field.
The access to the facility is easy as well with the new underground train and plenty of pedestrian walkways.
My minor small complaint is that the diverse food options are only available on the main concourse. If you are in the upper deck there seems to be only a few options for food. I ventured down to the main level to experience all the delicious options PNC had to offer.
The Pirates have a good facility, don't hesitate to visit.
