The kitchen
Two kitchens, one standard
Nicolai Wiedmer co-opened Eckert in Grenzach-Wyhlen and cooks there with a star in the Guide MICHELIN. Depending on the occasion, the catering comes from Eckert in Grenzach or from Krone in Inzlingen, and often both kitchens work together. Regional, with Asian and French influences, a vegan variant always included.

Region and family
Five houses, two generations
The Wiedmer family runs the WIO-Group in Grenzach-Wyhlen and Lörrach. The catering draws on the kitchens, staff and logistics of all the houses. That is why fondue for 300 or an ice-cream truck on a Saturday night works.
