Abstract Group recommender systems (GRSs) support groups of users to find items, e.g., restaurants, that suit, as much as possible, all the group members’ preferences. We consider a GRS scenario where a single member of the group, the organizer, uses the system to find and choose a suitable restaurant for the entire group. We present a novel GRS that helps the organizer to: enter the preferences of all the group members, recall them, and manage incompatible preferences. In the system’s experimental evaluation, we have found that the designed functionality for recalling group members’ preferences and managing incompatible preferences improve the quality of the organizer’s choice.
