a snack bar.
This term is a borrowing from European French into British English in the 1960s, as evidence from the London Times shows. In French, the term is widespread. First found in British English, it also entered, not surprisingly, Canadian English (see the 1971 and 1980 quotations).
See also COD-2, s.v. "casse-croûte", which is marked "Cdn (Que.)".
