Good point about Heineken.
The Amex has a Heineken lounge, adverts for it on the big screens and in the match programme, but it's not on sale at the concourse bars.
Get rid of Fosters.
I love the AMEX and the design of the stadium, but the only thing I would change is the design of the WSU concourse.
The centre part is not too bad, but the bar at the North end is too near the steps. There is a big bottleneck opposite the bar at busy times, fans obviously queue up to be served...
