Catering is a term used to mean food service. It has become an attractive sector in recent years and is also used in the sense of supplier of food. Companies that provide catering services are called by this name. In other words, it is the general name of the companies that provide catering and food production. Collective catering services provided to firms, schools, hospitals, small and large scale institutions, organizations and even to meetings with a small number of participants are considered under the term catering. It is very important that the catering service offers quality and professional solutions. For this reason, it is necessary to determine the best alternative considering certain criteria. Therefore multi criteria decision making methods are preferred for the selection. In this research, a decision model is proposed including five criteria and four alternatives for a catering firm selection. Considering the fuzziness of the process and as a novel approach, ARAS method is preferred and applied in picture fuzzy sets. Hygiene conditions and taste are determined as the two most important criteria and the fourth alternative is the best selection.
