We also had Spotless doing the catering at the Christchurch game - I don't know if it is the club thing or a stadium thing. I did not mind paying once as a one-off for an expensive plastic bottle of Tui beer ($8? can't remember) and the hot-dog was so-so OK but not cheap (over $10 with extras). I would not do it every fortnight at that price, so the issue of quality for money (and variety) is one of the reasons people may not want to drag a whole family along to a game unless they bring a picnic basket.
Off on a tangent. What I was trying to say was that there is more to a good game attendance than just where it is and how close to the pitch you can be. It is more of a whole product, both for the fans and the club. If there is a new ground in Petone but the same catering that may be OK for the club but not for the fans, unless local businesses get a shot at being open on a game day and being busy.
