Hi, there is no information on the Internet or I cannot find it. Only someone who travels here can verify it. This means it may never get added.

I assume you are interested party and maybe can even fill out more information than a random person.

I suggest to go to https://www.openstreetmap.org/ and click "Edit". I promise, it's simple. You just need to add a node from top menu on top of the house and then type "restaurant" in search to the left, then fill in the info and finally click "save".
