100% organic enjoyment

with responsibility

Since 2001, the Kolarik family has been taking steps towards sustainability and a greater sense of ecological and social responsibility. Therefore, especially the conversion to 100% organic was a personal concern.

Since 2019, all dishes are served exclusively in organic quality and with the reopening in 2021 also the drinks. Thus the restaurant Luftburg - Kolarik im Prater isthe largest organic restaurant in the world!


We want to create awareness, optimise the use of resources and minimise our ecological footprint.
