I reported in August that Google started to recognize addresses from web pages and included a link to Google Maps under those search results.
In this case, this search result for "Très Jolie" is the homepage of a business, so the address is relevant. By default, the map is not visible.
Google might use ManyBoxes to showcase some parts of a web page (think about a long page that includes sections) or links that create context for a page. In this experiment, Google shows an extended snippet and a search box for each search result.
