I just found that it has a website, too. The name is Friterie de Mariemont. For the anecdote: A few years back, Belgian law changed because the chip shops were semi-mobile affairs with propane stoves which tended to explode. The majority of the shops were classed as "mobile" - that is temporary construction by the side of a road on public land, and prohibited. The idea was that anyone who wanted to remain open had to construct a proper building, but most got around it by putting a veranda up in front. This one was moved fifteen metres from the road on to private ground, and then they put the veranda up.

[Bismarck] I see it - tucked into the back of the car park. We used to occaisionally drive the 15km over the border into Belgium to have chips for dinner at something similar They're everywhere. Our dog is called 'Chip' (or 'Chippie') after the food, BTW.
