I think I'll just take sandwiches and snatch quick, furtive bites in between dances, while hidden by massed ranks of Morris dancers. I will doubtless feel guilty, being the lawful good paladin that I am*, but if I phoned ahead and they said no, then I'd be stuck. (They do sell sandwiches, but they're of the very expensive served-with-salad-and-chips variety.)

* Not that any RPG has ever forced my character to decide whether to take sandwiches to a foody pub, or refuse to do such a chaotic deed, but now I kind of wish that one would. Are you listening, GMs? :-D
