This is definitely a solution; however it wouldn’t allow specifying what I wish to specify.
I’m not interested in tagging if a shop sells meat or not, since at least around here all of them (or at least the vast majority) do sell meat in some form.
What I wish to specify is whether they have a dedicated meat counter, which is interesting if you wish to get some specific kind of meat/fish/cold cut that is not generally found packaged.
Just as a putative example: I was searching for tripe for the world tripe day but since here eating tripe is not very common I had to go in several different supermarkets and butcher before finding it; thus I was interested in knowing whether the supermarket I was going to actually had a dedicated counter or if I could simply skip it altogether.
