TIL I learned about coffee-badging[1].

Sounds like, oddly enough, eighteenth century London when coffee houses provided venues for business transactions. People (ok men of the right class) toddled around visiting various offices and patronising coffee houses. Everyone knew the players. [2][3]

I think this might be a good development. Meet to drink beverage and achieve 'common understanding' in the sense of the Royal Navy. Then disperse to various private locations to actually carry out the tasks. Would suit a '15 minute' city layout very well.
