I prefer to go to the overpass end point, to show how easy is to extract OpenStreetMap data. It is faster than installing a plugin. For a talk, use the overpass Wizard to build the query. 1) Go to http://overpass-turbo.eu/ 2) Search for Zurich 3) Open the Wizard 4) Just type: bakery 5) Build and run query 6) Export as GeoJson 7) Add layer to QGIS (eventually points and polygons; calculate the centroids for the polygons in QGIS) Good luck for your presentation.
