Not much more I can say that hasn't already been said: one of (if not) the best MLB parks. Clean, beautiful, great sight lines, and the view of Downtown Pittsburgh/Roberto Clemente Bridge has to be the best in sports. Good food selection at SmorgasBurgh and good beer selection at Beers of the Burgh.
Can't wait to come back (especially once weather gets warmer).
TIP: Sit in Club or Upper Level from home plate to 3B to get best view of the city.
