Heinz turned closed restaurants' shutters into chef-voiced billboards

In China, tomato sauce (ketchup) penetration is roughly 30% — only about 30 of every 100 families have it in the kitchen. The reason is cultural, not a taste failure: Chinese home cooks prepare Chinese dishes and do not believe a Western ketchup brand has a place in them. Faced with that belief, a standard push tactic — food-science demos, advertising to mothers, e-commerce discounts — argues with a habit, and arguments lose against a stone assumption.

The moment that actually matters for the behaviour change is Chinese New Year, when families gather around home-cooked food. And that is precisely when thousands of roadside family-run restaurants (家常菜馆) shut for the holiday, pull down their metal roller shutters, and leave behind only a handwritten notice of when they will reopen.

For that week, Heinz turned those closed shutters — normally dead, blank metal nobody looks at — into thousands of its own billboards, each written in the shutter-shop owner's voice: 'Boss went home for New Year! Want my sweet-and-sour spare ribs? Make them at home yourself, with Heinz.' The shuttered local restaurant thus became the endorser of Heinz to its own regular diners, revealing 'the chef's secret': Heinz can make real Chinese food.

Turned closed restaurant shutters into chef-voiced billboards, using the local chef's trusted voice to endorse Heinz for Chinese dishes exactly when families cook.

Closed shutters are unmissable local landmarks during the holiday.

The chef's voice is trusted more than any brand claim.

The ad appears exactly when families cook the holiday meal.

The shutter disappears when the shop reopens, making the ad timely.

When your audience vanishes for a ritual, use the thing they all look at in that absence as your stage.

It won a Bronze Media Lion at Cannes 2025. By the entrant's own report it drew social attention and a 'certain degree of growth' in lower-tier penetration. The award marked a low-cost, street-level Chinese campaign winning an international craft prize, and pointed at a durable play: any brand whose shoppers briefly disappear for a cultural ritual can borrow the closed shop as its loudest moment.
