Traditional British Fair Food?

My partner is American and I was trying to tell her about traditional fair food but aside from candy floss and those lollies I can't think of any. I guess those small fried donuts? Talkin about small town fair here, not like Nottinghill Carnival which actually has amazing diverse food stalls. A Google search remains pretty fruitless. Please drop any foods you remember/can think of in this post! It's reaaaally annoying me.

Oh and I guess there was alaays a burger fan.
