Not a fan, could have been so much better. Just nothing special or iconic about this place.

Nationals Park is a pretty nice stadium to take in a game. Its a shame that catching a game there will mean having to watch the Nats play. The experience of going to a Nats game will get better as the neighborhood around the Park develops. There isn't much to do in the area besides the game, but hopefully that will change. The stadium is easy to get to, either by car or metro. Unfortunatley I noticed that the area is a mess to get out of after the game no matter which way you are heading.
The seating is comfortable and it doesn't seem like there are many bad seats. There are plenty of good options for food, although the prices are too expensive much like any Major League park. The screen over right field is impressive to watch, and they have nice scoreboards with plenty of information for an inquisitive fan.
