McDonald's has been directing people in Buenos Aires, Argentina, to its drive-thru restaurants by painting hungry mouths on nearby garages.

An outdoor campaign by TBWA/Buenos Aires selected homes with car garages located no more than 300 meters from a McDonald's with a drive-thru window, then commissioned well-known street artists to paint the facades of the houses, turning them into faces, with the only requirement that the doors of the garages would become large mouths. These were accompanied by a sign pointing them to McDonald's and the message: "Don't go home hungry."
