World café (conversation)

A world café is a structured conversational process for knowledge sharing where a large group of participants participate in smaller discussions groups organized around several small tables like those in a café. The process is usually organized in rounds: a few participants discuss one topic at each table for a fixed amount of time, then circulate to another table for a new discussion in the next round, and so forth.
