[Exile on Spencer St]

Half decent food at the Crown ground would certainly be a USP that very few other clubs could compete with.
Morecambe has (not quite literally) been dining out on having (allegedly) the best pie in the league for some time.
Mrs Exile and I mainly attend away games, and do not buy the c**p on offer at many other grounds a second time around.
As far as I can judge, the quality on offer has nothing to do with the size of the crowd or stadium. Big venues also sell inedible food and tepid tea, usually at even higher prices. FGR, for all the ranting about veganism, and Morecambe show it's got nothing to do with the number of customers, just the will to offer something slightly better than the worst possible food that a captive and hungry punter will eat.
