The latest Proefzaak in amersfoort

De Proefzaak in Amersfoort is the place where you can enjoy the good life. Either with friends, family or colleagues; there is always a reason to make your day better!

You can come by for a lunch or afternoon drink with bites in the sunny beer garden. Make your visit complete with a monastery beer from Kleiburg. Cheers! You can also make it easy for yourself after a long day at work by enjoing one of our affordable, local dishes.

You will find the Proefzaak on the monumental railway complex De Wagenwerkplaats, just behind the Amersfoort Central Station. Combine your visit with a VR Escape Room at our neighbours: The VR Room. Let’s go!

The menu

The best local products

De Proefzaak only uses fresh, local and fair trade products. We work toghether with PuurDichtbij, who deliver right from the farmer to De Proefzaak. That’s better for you, the environment and better for the farmer. 

Kleiburg beer

More than just a beer..

The name Kleiburg is more than just a beer brand: read about our story, the monastry and of course our unique craft beers. 



In De Proefzaak we serve delicious sandwiches for lunch or snacks with a drink.

We believe it is important to use local, fair and sustainable products.


What is a beer tasting room without good snacks? Enjoy these bites next to your Kleiburg beer. 

Some dried sausages, typical dutch snacks or a local cheese platter from Puurdichtbij.
