Many Items have the purple sticker if not on the main board where you order there is a price list over each booth and there weem to be more stickers shown there.
Do your self a favor and only order one of a kind, like us I was really disappointed in the potato cake at Ireland and ME and DW each got one, small, cold and a terrible taste. I love these at Church, Firehouse and Town Festivals but a the Ireland booth stay away or only get one to try. Perogi at Poland booth, MRs T's frozen put these to shame. And shrimp on the Barbi, I don"t like raw shrimp. Next year I will use the at the Kringla Bakri , or Ice cream places or for a Dole Whip.
The beer and wine OOP was great . And all our TS and CS we loved them all I'm not picky just didn't like what I mentioned above.
So my advice would be to look around and see what others are buying and see if they seem to like what they are eating I had poor choices but something has to be good there.
