To fix that please delete all the wikipedia=McDonalds tags from the McDonalds restaurants that show up inappropriately. Nominatim uses the wikipedia links to determine how well known a place might be and ranks places with a wikipedia tag higher. That naturally only works when the wikipedia tags actually link to a wikipedia page that describes the object. It leads to funny results when the link goes to category pages or, like in this case, to the company description. Alternatively: I've proposed a GSoC to overhaul the Wikipedia importances that Nominatim uses. Getting rid of this particular problem from the Nominatim side would be part of this job. For more information, see: https://wiki.openstreetmap.org/wiki/Google_Summer_of_Code/2018/Project_Ideas#Nominatim There are also two other topics proposed and if you have another particular itch you want to sratch, there are surely ways they can be transformed into a GSoC topic. Just send me a email or open an issue in github. It would be wonderful, if we find some students interested in geocoding this year.
