Jeg mindes at "building=apartments" godt må have butikker i bunden:

"A building arranged into individual dwellings, often on separate floors. May also have retail outlets on the ground floor"

(fra https://wiki.openstreetmap.org/wiki/Tag:building%3Dapartments)

I Gaden er der selvfølgelig tale om barer, men ideen er vel den samme?

På BBR står der ofte hvad bygningerne bruges til.
