When is a restaurant or cafe rebrand worth it?

It is worth it when the name, the room or the price are no longer what the poster tells, and the new guest walks into a different house. It is not worth it if the fault is a dirty poster or an old price, which can be fixed without changing the brand. Say whether the venue has changed or only the paper that announces it. In Madrid the logo is changed and the room stays the same, and the new poster is not believed. If the house has changed, the new poster comes from that room; if not, the current one is reprinted and brought up to date.
