Piazza is a idyllic cafe and bar in one of the most idyllic districts in Zurich, Switzerland. The cafe business was running well, but it needed more people visiting the bar at night time. So the solution was a small social media campaign: If you could proof that you checked in at Piazza on Facebook, you have been given a free drink. For promotion we simply stamped beermats with a the iconic thumps-up icon holding a beer. This is work was created under contract at Hochspannung advertising agency.
