Food wise, not a great area TBH. There is a Harvester near by if you like that sort of thing. There is also a big cinema complex near by with loads of chains. The club is doing a bbq though so that may be your best bet.
It has got to be about marketing ultimately. The product is great (much more consistent than footie), it needs promoting and advertising at all levels, not just SL.
I have spoken to people associated with Enfield FC where Skolars are playing at the moment who have never seen RL but really enjoy it (including the bloke selling burgers) but they would not have watched a game if they weren't employed by ETFC.
