Jeg vil ikke blande mig i den danske definition af hvad en kiosk i Danmark er, men:

(Tekstudsnit - Oxford)

kiosk 1 a light open-fronted booth or cubicle from which food, newspapers, tickets, etc. are sold. 2 a telephone box. 3 Austral. a building in which refreshments are served in a park, zoo, etc. 4 a light open pavillion in Turkey and Iran.

Ordet kommer fra tyrkisk og betyder pavillion, så mon ikke der er vide rammer for fortolkningen.
