I wasn’t aware of https://wiki.openstreetmap.org/wiki/Tag:shop%3Dfood

I understand our disagreement : in French, the word "traiteur" covers both activities you described. Until now, I used craft=caterer for places where shop=food food=prepared_meals is more appropriate.

After visiting the web site, I’m having a hard time choosing between activities but I lean on the caterer side (they advertise for weddings and events)
