Plugin: map with filter function

Im looking for a plugin that can show different resurants on a map.

​

Like on this page: [https://www.smagenafvest.dk/producenter](https://www.smagenafvest.dk/producenter)

​

There must be a filter function and the map must be nice to look at (or the possiblity to style it in coding).

​

The plugin must be free…

​

Hope someone can help.
