How do you collaborate with other venues in the neighbourhood?

A collaboration with another venue in the neighbourhood works when there is a concrete gesture: a one-day dish, crossed hours or a table that can be booked at both. Tagging each other out of politeness, with nothing for the guest to do, does not. Both venues agree the date, what is served and who answers bookings for that piece. A toast between neighbours goes out and nobody states the day, so the story stays a greeting. One joint piece with date, dish and booking link, published by both venues the same day with the same facts.
