a farmers store we go to regularly does a roast lunch takeaway, lashings of pork, bacon and onions in a bap with loads and loads of roast potatoes(veg is optional)!!
The thing for me at fairs is it has to be "walk and eat" food - not knife and fork.
Used to be a place sold brilliant bratwurst and knockwurst in Andover. Also like a good venison burger. Agree with Duncan on queues.
Another post-beer snack I remembered (bit of a theme here..)
When I first visited Prague it wasn't long after the fall of the wall, so the Western brands hadn't got in, nor the street vendors pushed out. THE most divine creation was a kind of half baguette impaled on a spike, squirted with mustard and then filled with a hot dog.
Lush!
No it wasn't me photographing my own snack in case you wondered.
Schasliks,currywurst or bratwurst with chips, frikadeles smothered in senf washed down with some Iserlohner pils. schnell imbis food lovely.
