Many blamed the Gault Millau Restaurant Guide. Published since 1972, the guide's cutting-edge criticism has made it the chief competitor to Michelin. A week before the chef killed himself, the guide had reduced its rating for La Cote d'Or, Loiseau's restaurant, from 19 to 17 points out of 20.
為了尋找禍首，多數評論者把矛頭指向剛出版的美食指南「高勒米歐」──自 1972 年創刊以來，這本作風前衛的評鑑一直是百年評鑑「米其林」的頭號對手──它在一週前把貝納・羅梭的金岸餐廳從原本的 19 分降成 17 分。
