oh duh! what a great idea! i should have thought about that.Go to a few events in your area and see what the higher volume booths are doing regarding CC-i.e., the booths that have a line and are moving it. Talk to a few owners if they have time.
I haven’t done any events in Chicago since the late 90’s so my experience from that time wouldn’t reflect the present culture.
Corn on the cob and turkey legs at Taste of Chicago come to mind. Although I remember thinking, “the heat index is 110 and I’m packed in here like a sardine. Who the hell wants a whole turkey leg?”the thing with street fairs is you need big flashy things that gets peoples attention as the see them walking down the street.
