• access a social graph maintained by an online social network, the social graph comprising a plurality of user nodes, a plurality of concept nodes, and a plurality of edges connecting at least some user nodes to at least some concept nodes, each edge representing a relationship between two nodes of the social graph;
• access a database associated with one or more third-party food-service providers, the database comprising a plurality of food-service parameters associated with the third-party food-service providers;
• generate one or more food-service recommendations for the event, wherein the food-service recommendations are generated based on (1) at least some of the plurality of event parameters associated with the event object, (2) at least some of the plurality of nodes and the plurality of edges connecting the nodes in the social graph, (3) at least some of the plurality of food-service parameters, and (4) preferences of each invitee to the event, wherein each invitee is assigned a weighting value;
• and
• send the food-service recommendations in ranked order to a client system associated with the user of the online social network.

A system comprising:

• one or more processors;
• and
• one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:
• receive an indication that a user of an online social network has created an event object for an event, wherein the event object comprises a plurality of event parameters, including a plurality of identifiers for a plurality of invitees to the event;
• access a social graph maintained by an online social network, the social graph comprising a plurality of user nodes, a plurality of concept nodes, and a plurality of edges connecting at least some user nodes to at least some concept nodes, each edge representing a relationship between two nodes of the social graph;
• access a database associated with one or more third-party food-service providers, the database comprising a plurality of food-service parameters associated with the third-party food-service providers;
• generate one or more food-service recommendations for the event, wherein the food-service recommendations are generated based on (1) at least some of the plurality of event parameters associated with the event object, (2) at least some of the plurality of nodes and the plurality of edges connecting the nodes in the social graph, (3) at least some of the plurality of food-service parameters, and (4) preferences of each invitee to the event, wherein each invitee is assigned a weighting value;
• and
• send the food-service recommendations in ranked order to a client system associated with the user of the online social network.
