Another year, another amazing edition. Proud to have brought to life the booths for Jack Daniel’s, Bols, Fluère, Diplomatico, Martin Miller’s Gin, Double Dutch and Gassier.

From production to logistics, 21 Agency was behind the scenes making it happen.

For 3 weeks, we brought a HelloFresh pop-up greenhouse right into the heart of Antwerp Central Station — making it easier than ever for people on the go to pick up a dinner package and turn busy days into healthier, easier evenings at home.

A quick stop on the commute, a fresh meal waiting later.
Because cooking well should feel simple, accessible and inspiring — even on your busiest days.

After Antwerp, we took the concept to Utrecht too 💚
Same mission, same convenience, same fresh inspiration.

Swipe through to see how we turned a train station into a destination for dinnertime.
