Princes ave has plenty of bar, cafes down there but is the opposite way to where you want to be going. There is george, Brickies and Parkers pub all right next to the stadium. Imo Parkers is the best place to be before and after games, although away fans might think differently.
Is Charlston still up and running? Heard something was happening to that place, but can't remember when?
