I've learnt a new word from it as well!
Vomitory (or vomitorium) - a passageway in an ancient Roman amphitheatre that connects an outside entrance to a tier of seats.
No prizes for guessing what I thought it was.
Does that mean we have seen the end of hotdogs and hamburgers and they will be replaced by strolling vendors shouting "Lark's tongues. Wolf nipple chips, get 'em while they're hot".
