(You can probably get these all over the world, I've just never seen them any place else except Derry)

A dish made from a layer of rice with a layer of chips (fries for all you crazy Americans) on top, all covered in lots of curry sauce. When I say covered in curry sauce here, I mean it. It would appear that to make a special the container is filled with hot curry sauce, then as an afterthought some rice and chips are added.

Although the first few mouthfuls will taste pretty good to the slightly intoxicated teen, only the fully intoxicated can easily manage a full one.

Some people find that they taste like acid.

They are available in most chip shops in Derry (N. Ireland) and I would imagine in many other places in the British Isles. Finding a special away from these shores is probably rare as most of the civilised world appreciates good food.
