A change in fast-food restaurant ambience can affect the amount of food consumed by customers, an unusual study has found.
Researchers decorated a section of a Hardee’s restaurant in Champaign, Ill., with indirect lighting, soft music, white tablecloths, even candles on the tables. The room was soundproofed, isolated from the loud music and bright lights of the adjoining standard interior. Only one thing remained the same: the menu.
