Don’t know how many “units” there are within the ground in total… but surely they all don’t have to be the same? Especially when there are two or more on the same level of the stand. One food, one drinks, one that has pies and pastries, one that does burgers/fries/pizza etc.
Be even easier to send a survey out by email that includes a link to reply with. Appreciate not every fan will get it but not a bad starting point.
