Need help making an interactive map

I’m a total computer newb, just assume I can type but otherwise can do nothing.

I want to create an interactive map for wedding guests, and also to just keep because people come visit, want recommendations, etc., and this way it can all be on the map. I remember being able to do something like this on Google maps, where you could create a map, name it, and share it. I can’t seem to figure this out now. I don’t want my other personal Google maps info on there.

To start, it will just be restaurants. But for extra points, I would love to able to have subjects (listed on the side?) that you click on that would light up the spots on the map. It’s hard to just color code for this since a restaurant might be in two or more categories. Thanks!
